For those wondering, you see how the rods are alternating diagonal? When the downward part of the bottom rod hits the table, it bounces up, pulling the other side of the rod, and therefore that rope, downwards. Rinse and repeat with every rod, all pulling slightly downwards on the ladder, and now it's falling faster than the other.

[@mikecurtis1111]

Since the rungs are angled, the table is causing them to flatten out, which pulls down on the rung above it. This alternates left to right, gradually speeding it up. Edit: Never expected my comment to get so much attention. To elaborate a bit, one needs to understand that even the ladder on the right will speed up after it hits the ground, just like the one on the left. The only reason you see the difference is because the one on the left hit the table (higher ground) before the one on the right. Also, to better see the pulling effect, don't just watch the strings close to the table. Look closer to the top of the ladder, like two or three rungs from the top after the top comes into view. You can clearly see motion in the strings that is not seen in the ladder on the right.

[@IdoAloni123]

The key thing is that the steps are angled in an altering pattern. As a step hits the table, a rotating force is applied on the step and pulls the next step, and applies a rotating force in the other direction. The interaction pulls all of the steps down every time a step hits a table. That's why the left latter falls quicker.

[@darshankumawat6668]

Exactly...👌👌

[@aspy6860]

Simple. Despite being dropped from the same height, the ladder on the left does not fall as far, the rungs hit each other and pile up while sometimes bouncing up and striking the rung above and jerking the string down. You cannot push a string up but you can certainly pull it down. The result is that the ladder violently piling up on the table pulls down and adds to the force of gravity.

[@willnash7907]

Basically, as each tilted steel rod falls, it bounces up a little on impact. This causes them to gain some torque that properls the other end downward faster. The taut string on that side allows that increase in speed to pull the ladder down slightly faster, while the non-taut longer string on the other end prevents the bounce from pushing the ladder up to slow it down.

[@bukscoetzer]

Two added forces 1) when the diagonally oriented rungs hit the table the impact causes a rotational moment within the rung and thus causing each short string to pull taught and impart a tiny bit of extra downward force on the string above it to arrest the rotational moment, thus adding to the Net downward force. and 2) As each rung hits the table the string attached to the rung above it is now exerting a small but significant horizontal force on the rope, which can only be absorbed by the rung above it (an additional downward pull), and thereby the swinging and bending rope pieces each add a bit of redirected acceleration force to the system, causing the net vertical acceleration to be greater than just the force of gravity on the ladder.

[@psyskeptic9979]

When the angled rings hit the table they exert a tiny accelerating force on one string, via angular momentum. When the next ring hits, it tugs a tiny bit on the other side string. So you get a series of tiny angular momentum tugs on the strings, adding to the g acceleration.

[@mr.zzzzzzzzzz3311]

[@galimbertino4939]

Exactly that. Thanks for you perspicacity.

[@dayashankarsuresh57]

The angled sticks ensure that tension transfer is not uniform at both edges in the next stick. This, in a way, generates torque, and this torque guarantees that the upcoming stick is pulled down faster. The pulling force accumulates and is most noticeable at the last stick.

Because the rungs are at an angle. Once they hit the table there’s a rebound effect that causes more tension on one side than the other. The tension yields a secondary “pulling” force that acts in conjunction with gravity, therefore speeding up the time it takes to hit the table which is higher than the other ladder.

Because of the arrangement of steps in the ladder as second one is free falling the arrangement doesn't effect the rate of flow but in the first case due to arrangement of steps touches the step coming above it and saves some time as the step above it needs to travel less and hence takes less time another reason is that the first one is piling up and the step above it has to cover less distance as compared to the second one

[@mitchellminer9597]

The angled sticks are the key. The center of mass of each stick is in the middle. When the lower end of the stick hits, the center of mass keeps falling at the previous speed. That makes the stick rotate around the contact point, and the far end of the stick increases speed. The upper end of the stick moves down faster than it did previously, and it pulls on the rest of the ladder.

The thing to point out is that the ladder rungs are angled. Once the angled ladder rungs hit the table there is a pulling action that takes place when one side of the rung hits, and the other side is pulled down because of the impact. This causes the rope of the latter on the left side to be pulled down faster.

[@rangerstyleisme]

[@snipershor6351]

The ladder's steps are not parallel. And they have a specific pattern. When one step of the ladder hits the floor, it creates an unbalanced force on the step, which produces a torque that pulls the upcoming step downward. The addition of force, say torque in this case, helps the ladder's top cap fall faster than the freely falling ladder.

This is not correct. The key point is that the "effective mass" of the left ladder is not constant. If you get the equation of motion for both, the right one is just a normal free fall, the left one has a decreasing exponential term.

[@carkindozin]

I was thinking the same thing

[@tylerdurden3722]

It's because the ladder has angled steps (planks). When the planks hit the ground, only the tip of the plank makes contact with the table, causing the plank want to rotate around it's centre of mass (converting the planks normal momentum into angular momentum). This causes the other end of the plank to also rotate around the centre of mass. But there's a string connecter to the plank above that, so it pulls down on the rope(gives a tugg and tension in the rope increases, all the way up to the top). The next plank is angled the other way, so it's the other side that hits the table first. So each time a plank falls, a downward tugg is given at the opposite end, alternating left and right. These tuggs add additional acceleration to the planks that are still falling, in the same downward direction.

As each rung hits the bottom, it creates a small moment of inertia (rotation) because one end of the rung lands first and then bounces up. When that end bounces up, it causes a slight downward tug on the other end (the side with the short string), which is still taut. This additional force causes a slightly greater acceleration to the free-falling object above.

It’s a “whiplash” effect. As the lower end of each slanted rung contacts the table it becomes a pivot point. The energy transfers to the opposite end of the rung giving a tug on the rope accelerating the fall of the ladder.

[@Chris_Sheridan]

@Tom Frain .. more precisely rotational inertia.

[@NoExceptions109]

ah so basically the slanted rungs act as lever pulling the upper rung down increasing the amount of energy transferred with each rung that hits the table/lower rung.

[@Chris_Sheridan]

@@NoExceptions109 .. the scientific explanation relates to inertia and momentum > each rung has a centre of gravity > during free-fall the impact with the table surface transfers momentum to the slanted rung that gains rotational inertia (during free-fall the strings have no tension) however, the rotational inertia causes tension in the string connected to the next rung which impacts with the table. The addition of these forces (through string tension) slightly accelerates the falling system of rungs. Momentum is conserved throughout - counterintuitively the table impact transfers potential energy into kinetic energy, some of which is used to accelerate the remaining rungs at faster than free-fall velocity.

A key to this trick is the alternating slanted bars. One end of a bar hitting the table causes the other end to pull the short string due to the rotation around the center of gravity of the bar. The short string is pulled and in turn the next bar is pulled slightly. As a result, the ladder experiences more pull (downward force) compared with the other ladder.

There is a slight "pull down" effect due to the angle at which the beams hit the surface, almost like a "leverage" effect. You can observe the additional tension transferred on the opposite side to the first side that impacts the surface. That extra energy transfer is enough to compile into a visible acceleration on the left ladder. Also, as more links impact the surface, if you focus on the further (up) beams, you can see the effect of the pull-down that I'm referring to. There are other observable events, such as the energy of the impact and the " force of the bounce" being transferred to the other ladder links.

Because every time a rung hits the table it wants to fall flat converting a tiny bit of its kinetic energy into torque yanking on the string.

When the lower part of the slanted rungs hit the table, it causes the lower side to bounce back up from the hit, which pulls the other side of the rung, the upper part with the shorter string, down faster, which is adding downward pull alternating side to side with the ladder on the left.

[@FarSeeker8]

Don't you mean, "from that fall"?

[@nkadimashiane]

Only difference I see here is that the one ladder hits the table before the other. The process was started earlier. But of course the secret is in the shape of the ladder. If the ladder was straight normal, then they would reach at the same time. But they are slanted and with every low rung that hits the table they is a slight pull on the opposite end. Causing a ripple effect of slight pulls with ever rung that hits the table to end up slightly a head of the other ladder. I might even venture to say if the left ladder was slanted and the other one was straight and they hit the table at the same time we would get the same results. I'm not a scientist, just a total logical guess. I stand corrected.

[@TheMotorcycleBoss]

Dad joke level 💯

[@timokreuzer1820]

The steps are tilted, so once the lower side hits the table, it will act as a lever, pulling on the above step at the opposite side. Since the tilt is alternating, this extra pull will be alternating between left and right, so on average both sides get a little extra pull down.

[@giusepesm]

Thanks. Another Veritasium video I just avoided watching!

[@Scotholomew]

Sounds legit

[@Reellron]

It won't matter since they're all in free fall and the lowest one cannot fall faster than free fall. I believe the answer is the rotating force as some have mentioned in the comments. When the rod is rotating, the distance to the next rod is decreased which creates an additional force to gravity. The rod starts rotating when the first side hits the table, the rotating force stops being applied when the rod stops turning or the other side of the rod hits the table.

[@roseville412]

This is like what that last guy said, but I'm words I can understand ✊🏾

[@nicwinegardner1182]

This is what I was thinking was possibly happening thanks for the explanation

[@TheMizfitMan]

The rungs are tied together. As each rung hits, the rope that connects them is displaced. Creating a small tug of downward force. This causes the next rung to fall a little faster. Which in turn causes a compounding domino effect with each rung that follows. Increasing the rate at which the remaining parts of the ladder fall. Making the object fall faster.

[@Kaikoura72]

Oh that's what I was going to say...

[@CivilizedWarrior]

Yeah, but presumably, the same thing happens when the other ladder hits the floor, no? So I would think it must also have something to do with the fact that it’s a shorter distance travelled to the table than to the floor.

[@BrewersYield]

@@CivilizedWarrior the other ladder hasn't hit the floor

[@29skatekid]

[@scooter7466]

He means when it does hit the floor. So in obvious terms yes the ladder that comes into contact with a surface first will technically be “faster.”

[@Protesusful]

These are rigid sticks linked with a flexible rope. The rope can't make any contraction force (it can't push upwards), but when a stick touches the floor, the other side of the stick moves slightly different and generates a pull force (downwards) on the rope that is transmitted to the upper sticks. Making the rest of the sticks move faster.

[@YT775]

The angled ladder rungs are forced to rotate around their center of mass when one end hits the table, this minor rotation slightly pulls on the cord on the adjacent end. So in sum a slight downward force along the cords is applied. In conclusion this only works if the rungs are angled like this.

[@stinbray1120]

Since the rungs are slanted when one side hits first, it creates a moment force which, in turn, causes the rope to be in tension. This happens at a slightly lesser magnitude in each rung.

[@tylos5588]

The rungs are angled in an opposing pattern, so each rung that hits, ( on the one making contact with the table ) pulls the string of the higher end when it tries to level, causing it to gain not only momentum but an acceleration type of force from the rungs pulling and driving the ladder faster, working in tandem with gravity instead of only using gravity to drive the ladder to earth

[@UncleRuckus7600]

I was thinking it was pulling itself down from the vibration in the strings. Great eye and explanation

[@danielmesa2102]

It seems to be converting part of its potential energy with the impacts into tiny forces that pull the strings alternatively.

[@adamsguy2704]

Bingo

[@Wlerin7]

Indeed, if you look closely you can see the upper rungs begin to oscillate slightly from the impacts below.

[@master_Wizard]

I agree

[@alakazam482]

Ok I think I've got a solution. Since each rung of the ladder is angled, one side will hit before the other. Since we dont live in a perfectly absorbent world, the part of the ladder that hits first is going to want to bounce back up. This puts a slight rotational force around the center of the rung, pulling down the high side that has yet to hit the ground. This repeats for each rung in the ladder, slowly making it fall faster.

[@WetDoggo]

[@bwryuun]

[@farrankhawaja9856]

The “perfectly obsorbent world” bit is wrong. The most natural situation is a perfectly elastic world where energy is conserved and things bounce back up all the way.

[@meta4282]

Very simple: The ladder rungs are not contacting the table square. When one end of the rung hits the table, it tensions the rope on the other side, basically helping to pull the next rung down a little quicker and if you repeat this all the way - one ladder will basically fall at the speed of " G + x ", while the other ladder will fall at "G" - if you can work out the extra downward speed, you will solve for x.

Tension theory. The tension in the ropes makes the stretched ladder more of a longer object, being dragged down by the weight of the lower part. Of course it also has more mass, making it harder to move, but there is drag to compensate for. The one that lands on the table experiences relatively slightly less drag so it falls the last bit a bit faster. I think. We'd have to test in a vacuum to rule it out.

My theory is simple : air resistance. Air resistance is affecting the one on the right more than the one on the left because that ladder is shielded from most air particles by the table. Remember that air resistance would directly oppose gravity( in this case) here so it could be the reason the left one is slower.

[@RudeComment19]

Take note of the tilted rods. The ladder on the left is hitting the surface with (X) energy and bounces back up with 1/2 (X) (newton’s 3rd law). Since the string just folds it does not slow the ladder. But, when the rod goes down on the other side (centrifugal force) due to the tilt in the rod. it pulls the ladder down on fully extended strings. It isn’t much , but still enough to quicken the fall.

[@zhinkunakur4751]

Okay , Here is my Attempted Educated guess : short answer : The increased acceleration comes from the gravitational potential energy turned into kinetic energy which works only in the special case of the ladder steps being in the way they are in the video . Details : The the special unparallel arrangement of the steps gives rise to an emergent property where parts of the surfaces of the step cylinder hit the ground at different times leading to acceleration of the other side of the step as a result of the effect of torque generated when the first side of the step hit the ground , this pulls the side of the step above and this effect compounds as more and more step hit the ground leading to the perception the last step falling with increased acceleration where the actually the acceleration is a step wise acceleration and not a continuous like gravitational but just smooth enough to trick the human eyes persistence of smoothness of acceleration / jerk /ms^-3 Experiment suitable for testing this hypothesis : a ladder with steps that are parallel to each other or any other falling linkage that doesn't share this special property. Experiment footage : this experiment too is on Dr. Andy Ruina's KZbin Channel , a chain instead of angled ladder is falling (in the shorts section) Thought Process : This effect is too big for the literature to haven't already captured in case of this effect also being present in the case of normal ladders , so the peculiar arrangement must be the culprit here and to gain further leads , Dr. Andy Ruina's channel would probably be a good lead for more footage and experiments and it was but there was no explanation there . Have a nice day Arnab

[@CrimsonRegalia]

My guess is that because the rungs aren’t parallel, when the first one hit the surface, it caused it to torque thus pulling on the opposite end. This tugged a little on the rest of the ladders and repeats every time a rung hits the surface. The tiny tugs compound until the difference is very visible. That’s my answer when looking at it on a per element basis. The math becomes a bit confusing when trying to analyze the system as a whole

[@theonewhoatebread4976]

It might be that because normal force is applied it falls faster idk it's confusing

[@Ronan_XD]

If you look at the end you can kinda see that happening

[@kingdomcome1617]

That was my first thought as well. The side of the bar ends that have shorter rope, pulls on the bar/rope above it when hitting the parallel table.

[@andrewsmith1735]

You're correct. The energy is transferred to the chain on rung impact, pulling the rest faster

[@linkedneurons3784]

I think you are... ...right. if you look at one side for awhile, you can see slight tugs on ore or the other side.

[@michaelcrawford1233]

My hypothesis is that when the first part of the ring hits, the linear momentum turns into centrifugal force. This means the outside on the rung will accelerate to keep the same centrifugal momentum. This accelerating pulls on the ladder increasing its overall speed. Over time it compounds to increase more each time a rung hits. To test this, you could do different ladders with different angels to see how they affect the overall speed. I hypothesize the more horizontal the rungs, the less the difference in falling speed. I would also be curious to see what the terminal velocity of an infinitely long ladder is. Another curiosity would be what would happiness to a ladder with nearly vertical rungs do.

the diagonal arrangement of the ladder rungs is important. One end always falls first, bounces off the table, rotates around the transverse axis, transferring energy to the higher end. This end pulls the ladder and after the whole process it falls faster.

[@Strike_Raid]

It's because the rungs are not level. When the tilted rung strikes the table, it tries to rotate about its center of gravity but the support wire resists that rotation and produces a downward pull on the support wire which accelerates the remaining assembly downwards.

[@4dbullshitpatroll6]

Yass. If a rung hits RHS first it adds pull to the LHS as it rotates adding speed to the LHS which pulls on the free falling rungs on the LHS. Ditto when a rung hits LHS first the RHS rotates and pulls on the free falling rungs on the RHS.

Each consecutive rod is supported by the one above it, thus enacting an equal downward pulling force on the one above a given rod. It’s under tension equally across both sides. The rods that land on the table enact an additional downward pulling force onto the one above them as their lower end hits the table, this causes the higher end to bear more weight- as it remains in tension. On an individual basis this force is minute, given the duration of this event, as well as the weight being supported by the table. This force, compounded across all of them, pulls it down faster than the other, which lands on the floor.

Because of the chains. On impact, the individual chain links are twisting and therefore affecting other chain links further up and dragging them down.

[@ghjkjjghjk4702]

i think it has to be air resistance, the one on the right has more contact with the air, the left one is reducing its air resistance because the chains have stopped moving through air. the left one has less air resistance overall, so its acceleration is faster by a small margin, hence the speeding.

[@D4nnyC4tz]

Its in a few other comments. To quote one "when one step of the ladder hits the table, it compresses on the longer string. and pulls down on the shorter string, causing a tiny bit of elastic energy which makes it go a little faster" So almost what you are saying.

[@bartermens8219]

Agreed, equal perpendicular spacing between the steps should greatly reduce the inequality in falling speed. Or a very precise spped-o-meter, or stopwatch should confirm the ladder on the left accelerates faster than earths gravity allows. The impact of air resistance from surface area, and proximity to the earth, I think can be neglected. This can also be tested by comparing the falling speed of a ladder above with a perpendicular ladder.

[@inflintity]

Good eye, the rungs are inclined with a shorter connection. One side hits first essentially pulling on the free fall acting like a lever, but the fulcrum is the short connector. You can take this a step further by formulating links that piled on top of one another, which ones didn’t and calculate the force needed to explain the difference in time between each ladder.

I think it is because the rungs of the ladder are angled. If you look at the very first rung that hits the table, the side that hits first adds a lever force that pulls the other higher side of the ring down. This pulls the long string taught and makes the overall ladder fall faster. I bet with a longer ladder the effect becomes more pronounced.

I am not sure but i guess i have an answer. When the entire apparatus is in a free fall, they all have a same amount of acceleration on each of them and hence no external force is acting on them (ignore air resistance). But once it hits a flat surface, due to its change in length of connecting each rods a torque is produced by the rod which provides additional force and helps it move faster.😊

[@theindiantruth467]

Due to the string arrangements of the ladder, it causes tension in the string when ladder pieces get aligned horizontally when falling on the table adding more force along with gravity and causes it to fall faster than the one in free fall

The individual rungs of the ladder are skewed, resulting in one corner always coming up earlier than the other. This causes the rungs to bounce off one corner and rotate them so that the other side falls down at an accelerated rate. This also accelerates the pull on the rope… In addition, the rungs also bounce back and forth (from our perspective) at an angle and rotate about their core, increasing the pull distance in the same amount of time.

My thoughts on this too. I think this is basically the same thing we observe in “the module effect”

[@bigfatzem]

exactly what i thought

[@matthewsnell2459]

As I thought, but couldn't have worded it that well

[@dutch_and_dimes]

This is simply a Principle in Tensile Forces, and there are 2 reasons why it's faster: • Both Ladders have Slanting rungs, which, when falling, causes angular momentum to be translated into pulling forces when the rungs tilt. This is accomplished because one section of string is longer than the other section on each alternating rung, causing shear rotation, which pulls the smaller string down when that rung section hits a surface. • The ladder on the left is landing sooner, and thus has rebounding momentum. This causes the ladder to bounce up slightly (you can't see it, but it is slight) when it lands. This rebound creates a slight pull, dropping the ladder down faster than it is falling. The same could also be said for the ladder on the right, but the only difference is one lands quicker than the other.

[@Aj-ge6ku]

Can you....explain it to me like I'm 5 years old.

[@ugandanknuckles3900]

I merely assumed air friction, but your response is good too.

[@luioskattusch3497]

@@Aj-ge6ku Here you go. There are two ladders, one is falling faster than the other. The first ladder has slanting rungs, which means when it falls it turns into pulling forces. The second ladder bounces up a little when it falls, making it drop faster. One ladder falls faster than the other.

[@dirm12]

How does a rebound upwards cause a pull downwards?

[@ordinary7sasha]

@@dirm12rebounding up to a certain point, then gravity does the work (a free falling thing sorta being slightly pushed down by the rebounding action). The right ladder was free falling without any interfering force but the floor, which came later than the left with the table.

[@Analoque444]

When you look at these small ropes, you can see that a contraction occurs on the left at the moment of impact. This suggests that the energy from the impact is reflected back onto the protruding part through tension This is especially noticeable on the second rung. I believe that even this small contraction adds up, causing the left side of the ladder to accelerate slightly. This effect is essentially amplified by the lateral slipping of the small ladder rungs upon impact, as they are outside the central axis. This also causes a brief tension, which pulls and slightly accelerates the entire ladder further. You can also notice that the rungs aren't perfectly straight and are uneven, which creates tension during impact. If everything were perfectly aligned-each rung evenly spaced and landing straight on top of each other-this effect would likely be much weaker, or might not happen at all.

Every time the low end of a rod hits the table it gives a slight tug downward on the other end, transferring stopping force to downward force. This speeds up the velocity of a chain ladder.

[@mikalnolan_3393]

this is answer is explained correctly in the most simplest of terminology

[@galahad695]

i thought the exact same thing, don't know if it's correct tho.

[@maximuschapman3852]

Yup

[@aviralrastogi]

So if the rods were perfectly horizontal, they would fall at the same rate?

[@jeromebuenoval7476]

regardless of downward velocity, two solid long objects with the same size and length, dropped at the same time at the same hieght, reached the ground, without a doubt, at same time, not faster nor slower from each other, over and over. If one of the stick like object#1 hit a floor or a table, it bounced back, while the other stick like object#2, move solidly streamlined or smoothly downward. However, an introduction of structural change in property, like the rungs on a ladder or short metal bars that form the steps but intentionally and alternately angled to the rope. This time, dropping down two air-gapped body of a rope ladder vulnerable to any slight air pressure, will definitely react differently upon hitting a table, unlike the previous hitting hard streamlined bouncing stick back and forth. Once the first rung hit the table: 1) it shorten the whole body length by same distance of each rung; and 2) it pulls the next rung by half the force and bounced half the force back. So inch by inch, the body length shorten as it continually fall a little bit faster.

I'm gonna take this conclusion and tell myself I made a scientific discovery today since they ended the video and didn't explain it... Lmao

[@aucklandnewzealand2023]

I had found myself in a peculiar situation where the lower rungs of a ladder seemed to defy gravity, keeping me suspended in the air as if moving in a direction opposite to free fall. However, should something strike the bottom of the ladder and remove its support, I would experience a sudden acceleration in my descent. Give it a try: falling without the aid of a ladder results in a faster descent compared to remaining seated on it.

[@FriendlyNeighborhoodGayGuy]

And it’s you Come here 😏

[@panditkakaal8110]

😂😂😂

[@IsmaelGarciaSerrano]

The tension produced on the short cable every time one step hit the table is added to the gravitational force

[@Clutched392]

it’s simple physics. only one side of each bar hits the table at once, causing a moment of rotational energy that creates more tension to the other side of the bar that hasn’t fallen down yet (basically pulling it down). because of this, the speed of it falling is exponential which is why you can’t really see the difference until the end

[@MarcoVenustus]

So it transfers kinetic energy to the bar above, making it move faster. Better explanation than the one I had in mind

[@TheGelatinousSnake]

In drunk idiot terms. First rung is slanted. Right side hits first, yanking the left side taught. So falling + yank is faster than falling alone.

[@Frederic_104]

Homie just called a Cornell professor's experiment simple

[@armourggeddon]

The very first rung of the ladder starts the process once it hits the table. As the low end of the ladder rung hits, a force is imparted on the side with the shorter cable attached. The uppward force on the side that touches first imparts a downward force on the short side as it rotates around its center of gravity. This “pulls” the lower side of the rung above it down faster thus marginally multipling the force.

[@seanb7124]

This seems like a reasonable analysis.

[@yourghostisagift]

Something like that

[@shinreed5927]

I was thinking less drag considering theres not much air to displace on th table while the other ladder is experiencing more drag. But your explaination sounds fairly accurate

[@Tra-vis]

Exactly it. The ladder isn’t straight for a reason. If it was a normal ladder (with equal sides), they would most likely fall at the same rate

[@berkutmotovlogs7954]

It’s essentially pulling itself down. The long line between each step hits first, causing the opposite (and shorter strung side to have a force applied from the step laying itself flat thus pulling the shorter side down, process repeats and repeats until finished

[@chewico3d133]

It has to do to the shape, when the first stick falls it applys a torque that forces the string down

[@sushrutwarekar9507]

That’s pretty cool. So if the rungs of the ladder were all perfectly horizontal and parallel, you wouldn’t see this effect right

[@VGleakss]

no, that is not correct

[@junkgrave]

No because this same exact effect is observed with two metal chain link chains

[@oscarmart1]

Torque is angular momentum/force, I see no rotational axis

[@martinlastname8548]

Can you prove that mathematically
