Always love Adam's reactions to disaster. "Whoa, Whoa whoa whoa! *Breaks into giggles*"

[@bvoyelr]

I just like how the square wheeled truck energetically jettisons parts every time they drive it.

[@keithrice39]

I love how Jamie is slowly working through the engineering that lead to caterpiller treads (which are basically one long square wheel that also has the advantage of round ones). Seriously, no joke it's impressive.

​@@JessicaH.97 because Jamie, for how much he was part of shaping my childhood, and I still like him... Is a stick in the mud. He's the boring twig in the mud in the hole in the stick in the mud. He's extremely level-headed 97% of the time. His "this is the most excited and energetic I've ever been in front of anyone who isn't my wife" is Adam's baseline. They're just too different, two incompatible people. And that's okay. You don't have to be everyone's friend. They could work together. They brought joy to many. That's all anyone could ever ask for. I do like when "friends on camera" are actually friends in real life. Back around 10 years ago I asked Nathan Fillion if he and Alan Tudyk were friends in real life or ever hung out after Firefly ended. He told me they had caught Game of Thrones together the week before.

[@barneyisabro]

@@JessicaH.97 Only partially true. Jamie is much older than Adam, and Adam is on record as saying their relationship is more mentor/mentee and professional coworkers than friends, hence them never hanging out. They have a lot of admiration and respect for one another, it's just not that kind of relationship.

[@Lagbeard]

It would be theoretically very possible to get a smooth ride out of square tires... But the speeds and forces required probably can't be provided with any realistic engine.

[@justanoman6497]

The lack of continuous contact would mean little to no steering I imagine.

[@samuel010898]

@@justanoman6497 or acceleration. The faster you go, the more time the wheel spends airborne. That’s probably why it started drifting as he tried to push it faster, with the lighter rear end drifting first. Not to mention it definitely completely trashed any unsprung parts of the drivetrain, the brakes falling off was crazy lol

[@aj7419]

Thanks for finally doing the full episodes!!!!!!!!!!!!

[@HardxCorpsxKali]

31:33 I have no idea how I never knew this as a kid but 100% the cars would’ve worked had they been able to fuse them together at the very front. The pivot point would’ve allowed the cars to angle while staying connect but the way they have them combined it’s completely rigid.

[@pyrho1]

Thank you so much for posting all of these full episodes

[@xXxJustCallMeM]

So much torque it twisted the chassis off the line.

[@xpndblhero5170]

Now I'm curious if octagonal wheels would work better..... 🤔💡😃 😂

[@Psychic42]

Yes. The more vertices you have on a regular polygon, the closer that shape becomes to a circle. You can think of a circle as a regular polygon, with an infinite number of vertices. so a pentagon would be better than a square, a hexagon would be better than a pentagon, and so on a so forth up to an infinite number of sides/vertices. There is also a cool video about designing a road that works best with a square wheel. kzbin.info/www/bejne/rnjbhIewlq53ac0 really fun video to watch and think about

[@justanoman6497]

@@Psychic42 I mean in the real world there is no such thing as a perfect roundness, they are probably just a couple hundred thousand sided polygons already.

[@Polysclips]

You're thinking in the wrong direction my friend... We need Triangle wheels

[@davidmccarthy6061]

Common experience, with round wheels, that higher speed over bumpy terrain makes it feel smoother. Still tough on the suspension though.

[@AleksiJoensuu]

I think Mythbusters tried this myth once, too.

[@LazyLemming2]

Turning the two cars might have worked better if there was a little bit of give/flex in the connection between them. Similar to a trailer. If two of the pieces of the cars were to wrap or hook around each other, there might be a little bit of a hinge.

[@narufemkyuufankid]

I was waiting for this episode!

[@michaelmayhem350]

It's a square one

[@tomplayz4209]

I say for the date night 90º turn if it was repeatable and consistent (turning left would always turn right) it should be confirmed

[@names_are_useless]

Are you a real person?

[@josiahsimmons9866]

It did remind me of Cars, "turn right to go left" and whatnot. I wonder how it could have been if they chose to test it a few more times. Though, maybe they did and it just didn't make the edit!

[@JediSentinal]

Yeah, if they can pull off a 180 you could use the same technique to pull off a 90 with some modifications. But that's getting into the weeds for an entertainment show lol.

[@cooljammer00]

I could have sworn there was a bit in this episode where they showed a car model with square wheels traveling on a road with big divots in it where the wheels fit perfectly in between so it was actually smoother than round wheels, but I can't find it now.

[@squidwardo7074]

I think it was on a vsauce video called "the brachistochrone" or something like that

[@andrewirving3982]

I remember it being an animation

[@samuel010898]

Some guy made a big video about it that became popular, but the problem with those designs (aside from needing an appropriate pattern to drive over) is that they don’t maintain constant velocity. This is easy to visualize; when the corner is down, the wheel has a certain effective diameter, but when it’s flat and the road comes up to match, it’s touching the wheel closer to the hub, so the effective diameter is smaller. So the odd shaped wheel maintains contact with the road, but it wouldn’t drive smoothly. Now having said all that, I’m going to try to find that video and see how wrong I am lol

[@KingSvenDeluxe]

Square wheels are the norm in Canada, that's why Jamie likes them.

[@John-be5vl]

Square wheels do work extremely well in mud. Whistlindiesel proved that a few years ago

[@Daniel-mk6ed]

For the square wheel truck wouldn't the differential change the offset stuff they were talking about unless you locked the steering or something

[@HardxCorpsxKali]

37:22 they mean they both turn the wheels in the same direction. If one driver turns left the other driver needs to turn his wheels to the first drivers right. Which is also left for the opposite driver. 😂 so they need to turn the same direction.

[@Bobal27]

26:43 I’m curious, did they try right pair offset 45 from left pair, or front pair offset 45 from back pair? Or was it just assumed that those wouldn’t produce better results than diagonal pairs offset?

[@Slotisfaction]

👏 enjoyed it, thanks for the amazing content

[@fredhurst2528]

I don't think there was really anything to be confirmed, they just wanted to drive a truck with square wheels for the fun of it.

[@heartofdawn2341]

This is a myth someone could easily push further on a small scale. Get some 2wd and 4wd RC cars, race them on a track through different conditions, and then see how they compare with square and round wheels.

[@carlsoll]

25:23 Soooo funny 😄 how well this worked so quickly, love it :D

[@AleksiJoensuu]

The 45 degree offset would be... offset by differential slip. Unless maybe you had a car with lockable front, rear and center diffs (maybe this truck does?). But then I guess you'd destroy the diffs themselves pretty quickly 😂

[@gkk18300]

I’m so glad they had time to prove that Canadian wheels do indeed work

[@RoniRonkoKovatch]

[@stokermeister3]

I’m certain the Borg would like that 😁

[@williamdowling7718]

As a kid i never realized how much of this show was basically just preempting the complaints that fans would have. Now i can see how much unnecessary stuff they did seemingly to get our ahead of the kind of fan who would write in and say "yea but you didnt offset the square wheels and thats why it didnt work." Adam and jaime undoubtedly have plenty of car knowledge to know that unless they welded the differentials together, the wheels on a car/truck can spin at different speeds and thus offsetting the wheels before driving is useless. But if they just said "that wouldnt matter because..." It wouldnt be as entertaining and engaging as doing the small scale tests and then showing the silly idea in practice at full scale so we can SEE why it doesnt work. I appreciate the hell out of fhis show and i always have.

[@FalloutJack]

9:56 What are these? No idea, but if they happened to get the cars off of Top Gear, it might've been when Clarkson, Hammond, and May decided to build James Bond cars on a budget. 😁

[@KingSvenDeluxe]

You'll never get a smooth ride considering that only the corners of the "wheel" would be able to contact the road. Not enough rubber to road contact to get up to the required speed.

[@heartofdawn2341]

Square wheels would be an utter nightmare on ice or in the wet, or when going around a corner. And you'd need to keep all the diffs permanently locked so they don't end up out of sync, which only makes everything else so much worse.

[@hizzy70]

The newest video you guys posted is unavailable in the Usa, just a heads up

[@psinjo]

at 3:30... i've always wondered about the 'mythbusters blueprints' but that looks like a table you can just draw on? or is it a piece of paper on top of the table? sorry i'd love to get more information about it, anyone know?

[@stgigamovement]

Paper on top, because the blueprints were saved.

[@Slotisfaction]

Idea! Connect 2 cars together with the steering and acceleration combined, then just use one car to accelerate and steer both.

[@Terminator484]

Gotta admit, seeing an Audi of that body style & color on Mythbusters is a little weird... since there's an identical one parked outside my apartment.

[@c911darkwolf]

Square wheels where the tread moves around the rim, instead of the rim turning have a lot of promise, greatly increasing surface area.

[@brj_han]

They obviously need to try triangular wheels that will dig into the dirt better. Lol...

[@tideatmilehigh2727]

Its a well known fact that all Canadian cars have square wheels.

[@ThePerson06]

I swear I’m surprised that I haven’t seen more references to this

[@CarAudioEnthusiasts]

ok so, the tire falls at 9.8 meters per second, SO at Some speed, the wheel would be rotating fast enough to Beat gravity and go corner to corner. the PROBLEM is even once it was totally smooth since only a tiny portion of the WHEEL is making contact with the surface, AND its Impacting each time, there is a total loss of traction both forward and side to side. so its essentially floating. this brings the other issue, once it STARTS floating, its no longer able to maintain speed. its like trying to take off in a wheel powered airplane.

[@bugnokumaguy]

Garage 54 did this already a few years ago, and also tried to improve upon it just over a year ago.

[@BlindmanDru]

You can weld aluminum, you have to tig weld it instead of mig or stick

[@timelytorch]

Yes, you can weld aluminum, It is just much harder to weld aluminum to steel. Also depends on the steel. You can't weld aluminum to carbon steel for example.

[@BarbaraStarling-ye2el]

i reckon they would do well on stairs

[@JosephGores-qu1qw]

Date night car....My 2000 crown Vic is just under two tons. Would be lighter than that with bumper removed. So I doubt this is 4 tons ( since the other car would be lighter). Oh, and it has traction control, which would minimize slip

[@tonycook2347]

For the hill climb, it wasn't in 4WD for the round wheels. it was for the square wheel though.

[@creepywolf9278]

it would definetly work if they make like 4 of them on each side, but angled differently, so that you would basically drive on tracks

[@zhabiboss]

Technically, if you achieve speeds just below the first cosmic velocity on the car the ride will be smoother than that on a car moving at legal speeds, because you will begin orbiting the earth
