How Does The Ruler Trick Work?

[@Mozarkian]

when I was a kid, I watched "Mr. Wizard's World" religiously. He performed this same experiment by putting a large newspaper over a 2x4 and then hitting the end of the 2x4 with a large hammer, snapping it. I was amazed.

Interesting enough the paper is not needed for this to work, if you lay a rulers up tight on either side of the original ruler and another one at the back edge it also works. the idea is to block the air from getting under the ruler. It is the atmospheric pressure on the ruler itself, 14.7 PSI which is enough to do the trick.

Well, it's 14 pounds per square inch; however, it's not a perfect suction cup because part of the paper comes up when it lifts, so you'd have to solve for that. I would guess that the square inch over the ruler is the section holding it down.

Yeah, it’s 14.7 pounds per square inch. So, for a piece of paper that’s 8.5”x11”, that’s 93.5 square inches, which is a total of 1374+ pounds of pressure. It adds up quickly.

[@eklectiktoni]

As soon as he did it, I thought about how paper always seems to "stick" to smooth surfaces like a desk. I figured if the surface was rough it wouldn't work. Glad to see I was right. I wasn't sure what the scientific explanation was (I was wondering if it was like surface tension or whatever allows bugs to climb walls), but I did realize it had to do with the paper wanting to "suck" to the desk.

I think you have a missunderstanding about the real reason bugs have naturally sticky legs and those mosquitoes that could walk on water is bc of water tention (or smth like that) the real reason why is because when you do it fast it creates a vacuum under the paper making the paper be sucked by the vacuum underneath it also Wild K its the same when you do it fast or slow its a matter of grip

I was watching this video at my desk so I didn’t even have to stand up to try it out, I already had all the materials at arms length reach lol. Its also kind of funny that it only works when you hit the ruler fast because it kind of makes it feel like oobleck

[@aComedicPianist]

When you crumpled up the paper and tried the same experiment again, I reasoned that it had to do with the large amount of surface area the paper was covering when it was flat. After that, I thought that it was because there was a vacuum underneath the paper. You move the paper quickly, but since there is nothing to replace the empty space with it, it decreases its pressure. I usually keep forgetting that it’s technically because there is a difference in pressure whenever it’s in a normal atmosphere instead of just a larger pressure difference in general.

[@ΓιώργοςΚαπάτος]

This experiment can also be repeated with some alternatives such as: 1. Ruler length (much shorter or much longer) 2. Paper size (larger or smaller) 3. Weight of the object falling on the ruler (for example a washing machine or a refrigerator 😜)

Great teacher, and ( note I use word and, not But) I have some to say about: pressure is the same on top and under the paper, but, her goes but, air flow underneath paper is tangent to the paper itself, so according to Bernoulli^s principle pressure will be less under whole paper sheet keeping it down, all your explanation is great, just wanted to bring about this well knwn law, same happens when you use a hand blender in a liquid close to the bottom, you can lift the cup with the blender , keep on

I mean, you could always use the flexible shell/membrane aproximation to estimate the deformation coupled with an compressible irrotational method for the fluid dynamics and get an FSI system of equations (maybe even incomprensible given the low speed). Probably the system will have something like aerodynamic mass, structual mass and structual stiffnes. But looks like too much work for such a basic experiment

[@DANGJOS]

@@calvinlee1127 Be careful. P is not atmospheric pressure. P is atmospheric pressure minus the pressure under the paper. You can't assume the paper has a perfect vacuum underneath it. Even just half an atmosphere would allow a considerable amount of force.

[@Evolved_Skeptic]

You might want to mention the actual value for the air pressure (at sea level) is 'round *1.04 kg/cm²* (with minor variations for air temperature). So for an *A4* sized piece of paper - with the surface dimensions of *29.70cm* x *21.00cm* it gives a total area of *623.70cm².* *623.70cm²* _(Total Area of the _*_A4_*_ paper)_ x *1.04kg* _(Air Pressure per cm²)_ = *648.65kg* _(Total Air Pressure pushing down on the entire sheet of paper)_ Nearly 650kg of mass [ Edit ⊚ ]... I'm surprised you didn't snap the steel ruler. [ I've broken wooden rulers doing this as a kid. ] ⊚ - *650kg* Mass = *6374* Newtons of Force.

Well yes but no, if you do it instant, you'd have to deal with 6000+N but there is not such a thing... It's still a high force, don't get me wrong but it's not 6000N (when you do it slow, it also won't nearly be that force)

[@hammersbald7612]

What you are implying is wrong on so many levels I can't even... static air pressure has nothing to do with the vacuum created by lifting the paper.

[@CarbonTech19]

I spent over 10 years, of my 30+ year aviation career, working in the composite shop of a major airline. We used to repair all the removable, damaged composite structures. After we got rid of the damage, we had to replace the fibreglass, Kevlar or carbon fibre we'd removed with equivalent materials and use the approved resins to replicate the structural integrity and performance characteristics of the original layers. Once we had all the multiple repair layers cut, properly orientated (the direction of the warp and weave), soaked in resin and stacked in place, we'd do our bagging. This consisted of laying a release film directly onto the wet repair, followed by a felt-like bleeder cloth (sucks up excess resin) and another thicker layer, the breather cloth, to allow easy air flow as the vacuum forms, and finally an impermeable, stretchy bagging film held in place by sticky bagging tape around the repair area. Then we'd hook up our pressure gauges and vacuum lines, seal up any leaks we'd missed along the bagging tape, and watch the Earth's atmosphere press down on that repair area at about 14.5 pound per square inch. A 1 foot square repair section would have the equivalent clamping force of over a ton (2088 lbs) of weight, evenly distributed over its surface, and thus compressing the repair layers and squeezing out the excess resin sufficient to replicate the original manufactured characteristics. (there were also temperature controlled heat blankets and or lamps involved to cure the resin at the required temperatures). Side note: the pressure was so great, that the outline of a piece of masking tape, used to hold the release film in place, could often be seen through the multiple layers of bleeder and breather cloth. And that's how I knew why the paper was holding down the ruler, lol. Interesting to note this atmospheric pressure was the same regardless of the repair area's orientation-upside down or sideways made no difference, just like you'd get crushed from all directions simultaneously at ocean depths. Also interesting to note that similar composite repairs, in mile high cities like Mexico City or Denver, can never get the same degree of compression and will always be intrinsically weaker. One last thing. Some of the more critical parts, requiring higher performance, are manufactured and cured in pressurized ovens where the vacuum bagging is being pressed on by significantly more than sea level air pressure. Their engineers give limits to repair schemes that can take place without using a similar pressure vessel. Thus ends my Ted Talk, lol.

[@RealCadde]

This was instantly intuitive for me the first time i saw it. The same way as the hanging a hammer from a ruler trick works. But when you explained it, all i could think of as a cool way to explain it was... It's the weight of the air holding it in place. All that air from ground to top of the sky is pushing on that piece of paper.

[@PabloGarcia-pl8yy]

I only watched the KZbin short version of this but if I remember correctly, you said that the weight is 14lbs per square inch? So if you where to slap the ruler down as hard as you can, the ruler would snap? Just curious. Edit: Am now watching the video again and now realized you’re using a metal ruler so it wouldn’t snap but could you bend it?

[@dev-9962]

[@abhirams2288]

Yaa it does break, have seen those in some other videos.....(if it's a plastic scale)😅

[@ethanmye-rs]

Air pressure depending on where you live is about 14.5psi, 8.5x11 paper is 93.5 in^2, for a max differential of 1350lbs. Of course, this assumes a perfect seal and a vacuum underneath the paper, but I wouldn’t be surprised if a thin ruler thin paper could have a decent impulse.

[@analkalinne]

I think you definitely can, if you have multiple sheets. With just one, the paper may rip before the ruler breaks.

Yes you can break plastic and wooden rulers this way. But so you don't waste money on rulers, you can also use this trick on inexpensive wooden paint stirrers.

1:15 into the video. i am guessing atmospheric pressure, underneath the paper is kind of a seal, when the ball hit the ruler, the other end of the ruler will try to lift off the paper. the lift will create negative pressure underneath, atmospheric pressure will push the paper down in turn pushing down the far end of the ruler.

This seems similar to the ground-effect on which Formula 1 cars rely to increase their grip while moving at high speeds.

[@sparkee4954]

in a way it is indeed similar but with the ground effect it's kinda like the opposite. ground effect happens because of the venturi effect where the rapid air flow gets compressed and creates a vacuum. while in this one the air expands.

[@kristiankrekac1112]

Putting some drops of water between 2 glasses, makes it really, really hard to take apart by pulling them away from each other. (no sliding) It's that because the water preventing the airflow between the 2 glass? Or is there any other force than the atmospheric pressure?

[@westonding8953]

Intermolecular forces of the water are involved. But probably to a relatively smaller extent. (Yet hydrogen bonds are really strong.)

[@CommanderNissan]

Water does have extremely high surface tension, so that may play a large role. So water doesn’t act as a very good channel for airflow. It’s also harder to drastically and suddenly shift the volume (temperature/pressure) of liquids compared to manipulating gasses.

[@giovanniquargentan6198]

The drops of water allows you to better expel all the air in between the two glasses, and then atmospheric pressure keeps them together
