Lego Tires vs Tracks - Pull Test! Small, Medium & Large! 4K

[@Carlifurafollas]

The issue running them both over the carpet is that plastic tracks are much more prone for slipping than the soft rubber tires

[@GazRsExtremeBrickMachines]

Yeah I did have little studs on but they slipped though the top layer of the carpet still unfortunately. With more weight on the vehicle it would have helped a lot :)

[@IceSki117]

​@@GazRsExtremeBrickMachines That makes me wonder how feasible it would be to coat the ground contact portion of the tracks in the same rubber as the tires.

[@GazRsExtremeBrickMachines]

They would be so grippy, the big Lego tyres are so soft when I had the tug of wars it would leave quite a bit of rubber down. If you put them on an rc car I think they’d melt in 10 minutes :)

Mf I thought it was sand till I read this comment

[@Eternal_Boredom]

@@Brando1345 are you high or some shit

[@RiedlerMusics]

since grip is the main problem here, not power, laying a brick *onto* the machines could provide much better outcomes. I suspect the tracks would be affected more than the tyres, since they distribute their weight over a much larger surface area, decreasing grip per area

[@GazRsExtremeBrickMachines]

Hey definitely! I tried a brick on both and the tracks were unstoppable until the force was too much for the track connections.. so I soon stopped Thanks for the comment :)

[@RiedlerMusics]

@@GazRsExtremeBrickMachines that's cool! will you make a follow-up video with proper weights? You know, those weights for scales and stuff, so you can add exactly 100g or something like that.

[@AlexMonas]

yea! or provide the weight of the 2 machines, at least in their "final form" Without the knowledge of their own weight and therefore the own force with which the machine is pushed into the carpet, that beautiful experiment (!) is missing one little bit of information.

[@jdridesbikes]

@@AlexMonas Weights of the machines were provided at every stage of the build. Final build weight: Tank (Large) 4.2 Kg, 4x4 (Large) 3.9 Kg.

[@KewneRain]

I wonder if the load distribution would have made a difference as well, instead of changing the grip pattern, change the pressure of the load

[@DysfunctionNoMore]

Would make a huge difference. An even distribution would ensure there is no angle to the dead weight. In the video, it was pressing hard into the carpet right behind the vehicle, and basically lifted off the floor at the rear.

[@ThePinkPanth3r]

​@@DysfunctionNoMoreI would have liked to see a brick placed on each vehicle, I think it would have helped both tremendously.

I came here to say exactly this! It was kinda frustrating to be honest!

[@Floris_VI]

Thats exactly what i was thinking too but i think the point of the video was more about surface area than actual total grip

[@Zorro9129]

The 4x4 had surprising results, though with the way the axles bent, I doubt it could survive under such heavy loads for long!

[@GazRsExtremeBrickMachines]

I added a little weight for grip to it after the video and let’s just say it was on the edge already lol. Thanks for the comment :)

[@buzz_4stroke192]

I don't know if I'm more amazed of the strenght of lego pulling power, the little rope or the plastic tab from the lid where the bricks lay on. Great experiment tho!

[@AdjacentBandlab]

For the tank treds I think that if you put the black 2x1 connectors pieces on the treds, It might have increased the grip because the connectors would have been digging into the carpet instead of the technic bars just slipping (Kind of like a cars tires on ice, the tires starts to lose grip and well slip) theoretically the connectors would prevent that problem, as if you were to put chain over the tires on the car I used as a example. If you put the connectors on to the technic bars and then supported those bars on the side that would most likely need to be supported it would improve the tanks grip as it already has the torque to pull more of those bricks. Just an idea that had probably been in some others people's minds that I thought I wanted to share because I felt like typing out a problem that could be fixed, even though you've probably already thought of the idea I wrote about. Oh and I love these videos I have a th8ng for mechanical moving parts it very calming for me to watch gears gears move. Well have a good rest of your day or night and I hope your having a good one.

[@jzcapets]

Could almost do a whole episode on this one. Various different "tread patterns" on the tank treads...studs, connectors, technic beams, etc

[@AdjacentBandlab]

@@jzcapets yeah probably could, but equipment and time is what I need.

[@GordonWrigley]

I want to see the small tank with a brick on top of the tank. The problem here is all traction, a heavier vehicle would be less inclined to slip.>>

[@GazRsExtremeBrickMachines]

I did try afterwards :) you’re right it’s about weight, the string pulling the rear down under load also helps the tyres more than the tracks. If both vehicles weighed 10kg the tracks would probably pull double the tyres if Lego wasn’t made of plastic lol

[@alex-q8-q9]

Well, tanks aren’t designed for pulling necessarily. They’re made for rough terrain so they won’t get stuck. Obviously the 4x4 will win here as it has a much better weight distribution than the tank.

[@GazRsExtremeBrickMachines]

It was still close :), with extra weight on either vehicle the bulldozer tracks would have an advantage eventually

[@Grychon]

I was watching the wheeled vehicle as it took up the strain with the heavier loads, much more and it would have twisted itself apart. I really like the tank, just something about a tracked vehicle makes me smile. Thanks for the video Gaz 👍

[@GazRsExtremeBrickMachines]

Hey Lee cheers mate! Nice to see you post! I tried the 4x4 with a brick on and it destroyed itself after another brick was added lol. The tracked vehicle with weight was unstoppable until the tracks gave out. Love tracks too!

[@batman3698]

I'm most impressed by the plastic tab on the lid/sled and the wire or string used for pulling

[@bestbattle]

The wheeled vehicle looks so cool when loaded

[@GazRsExtremeBrickMachines]

Hey there :) Amazing grip those tyres provide, really soft rubber.

[@VandykRina]

I want you to take the teris vs traks cars but with krashes

[@DesertVox]

I didn't realize how more wheels = more traction. I thought the traction would just be more distributed, not amplified. I guess the added weight of the wheels and support is what adds more traction. If the same weight was added without the additional wheels, my guess is that it would have the same traction.

[@jamesodwyer2115]

To maximize friction (traction) you can maximize surface area in contact with the ground Edit: as Jimmyprior pointed out, this is entirely wrong. Surface area has no bearing on frictional force.

[@yourcurtainsareugly]

@@jamesodwyer2115 What's the physical justification for this? Broadly speaking, friction in generally limited by the normal force and material properties, not based on the contact area.

[@GazRsExtremeBrickMachines]

Yeah I was intrigued by this. What helps with the pulling is the string is pulling the vehicle down at the back. If the string was horizontal like in a tug of war I’m not sure how much extra help the tyres would give.

[@jimmyprior]

@@jamesodwyer2115 increased surface area shouldn’t increase frictional force. The equation for frictional force is coefficient of friction multiplied by normal force. I think some other things are going on here that are causing the discrepancies (wheels are heavier, sinking into carpet)

[@eastcoastscumbag3307]

Tractors and other farm machines do this I always thought it was to distribute the weight over a larger area so if you hit a slick spot it doesn't start slipping and sink you to the diffs. There's also the option for instead of two standard tire and rim to have a single fat tire. Some silage trucks run fat tires instead of duals, call them "floatation tires".

[@MichelleStanley-y4g]

The wheeled vehicle looks so cool when loaded. Back when we needed him most..

Alright, guess we need Lego beadlock wheels and tires now.

[@bassface84]

[@garethdavies2973]

Watching the 4x4 dig in and flex upon taking the load is awesome. I wonder if the tyres had some sort of bead lock to stop hub spinning and extra vehicle weight how much could be towed until major component failure 🤔. Great video thank you

[@GazRsExtremeBrickMachines]

Thank you very much! I was so close to glueing them but in the end I thought that’s how it is. The weight was so much, it was tough to drag it with your arm as the friction was so great. I can’t believe it didn’t break haha :)

[@IstasPumaNevada]

Seeing those doubled-up tires makes me want to go drive a farm tractor.

[@DarrenBoxhall]

I want to see it ran again, but with weight added to the machine, like a brick added to them to force the wheels/tracks down,

[@GazRsExtremeBrickMachines]

Hey Darren I did try afterwards with a brick, the 4x4 was right on the edge already and the hubs just started spinning inside the tyre. The tank could have pulled quite a bit more though :)

[@thatgreenleaf9817]

I would LOVE to see this with the lego air engines see how well those would perform on these conditions

[@rctv9974]

You're back!!

[@GazRsExtremeBrickMachines]

Hey there! It’s been awhile :)

[@PioneerRifleCompany]

I like the content and you spent lots of time putting this together. That is much appreciated., Your frictional coefficients between the tire contact and track contact are not equivalent. Also, the tire vehicle creates a moment of traction that is not spread equally across, especially, the rear axle. The outside tires create a V structure which creates a non-linear friction curve for the tires closer to the apex of such V, which is modified by the hitch attachment point. Try an experiment where you move the hitch point under the axle to the center, or just forward, of the rear axle. Make sure the non-static linkage (tow rope) has a trunnion or vector block under the rear axle.

[@iamhugry]

On the wheels you can see they are all toeing inwards, for max strength I reccomend toeing them outwards when stationary that when they pull themselves inwards they straighten out

If lego tracks actually had some decent grip pieces (they have always been awful on fabric surfaces) then I reckon it would've been able to handle more before needing to be modified

[@GazRsExtremeBrickMachines]

Yeah even with the little rubber studs they were sliding through the top layer of the carpet still. With more weight it would have been great but I think plastic would start snapping :)

[@Half_of_The_World]

@@GazRsExtremeBrickMachines I thihnk I may have to design some that can be 3d printed with that weird rubber fillament, because from my tests that stuff is pretty grippy.

[@GazRsExtremeBrickMachines]

That would be great, I think my little rubbers have dried up a little too compared to when they were new and tacky.

[@jacksonspeaker3474]

Dang the poor lid it looked like it would snap at any moment twords the end and man was the 4x4 squatting i think if it had a metal rod for the axels it might have been able to do one more brick i also think if they were laid out on the lid instead of stacking both would have done more

[@GazRsExtremeBrickMachines]

Yeah the lid broke as I move it afterwards lol. Things here were right on the edge of braking as when I added weight onto the vehicle it didn’t go so well lol

[@davidhawthorne9637]

With a little weight on the front of the 4x4 it would have done much better. Especially once you added the 1st and 2nd set of extra tires the front tires were not doing much due to weight transfer. If you had sat 1 brick on the front I think it would have pulled quite a bit more or twisted an axle trying.

[@GazRsExtremeBrickMachines]

Yeah definitely! The front was in the air which is why I left the front axle quite supple so the outer tyres still touched(probably did very little still) I’ll make a giant 8x8 truck soon with more weight just to see how much weight it can pull before lego breaks :)

[@henryknox1186]

You need to add weight to the front. The front wheels and tracks are lifting up. You have to keep the front down.

[@adamrath8109]

Nice video! It would be cool to see a food scale or something to measure how much force it takes to pull the sled.

[@GazRsExtremeBrickMachines]

Надо было попробовать поменять направление протектора на колесах. Интересно, изменился бы результат?

[@nicolorech8690]

The tires are mounted wrong, the "arrow" should point back(looking from the top)to increase the grip

[@waynemeyer1195]

Seems like a lot of folks don’t understand the capabilities of tracked anything. It’s superior in nearly every aspect. It would make almost no difference on what surface the test was on or load placement on the sled (lol). The test is tracks vs tires, 9/10 tracks win every scenario. There’s a reason the largest ag tractors are tracked, there’s a reason tanks are tracked, there’s a reason the biggest strongest dozers and excavators are tracked, there’s reasons folks…

[@MereanaM-]

adding wheels does not increase friction, they ride better due to the extra weight

[@earthenscience]

It would be boss if you could somehow put some rubber thingies onto the treads, so that they would actually be useful. Can you make a video where you somehow rubberize the treads? I don't know how.

[@granderwishes]

thank you for tossing the "studs" on the track, was gonna comment that I thought tank treads had at least equal grip potential to tires with the... claws? (sorry don't know actual term) on most treads from what I saw. Flat tread, especially as close together as those look, I would imagine wouldn't be effective in any situation really.

[@someinternetguy955]

It isn’t the addition of tires and tracks that is making them pull more, it is the addition of weight. The term is ballast, and simply means to weight the unit to put the power to the ground. Look up ballasting agricultural tractors for more information. Simply put you need to have the proper total unit weight and front to back weight ratio for the most efficient power transfer, which was off for the tires unit as you could actually see it shift in the last couple pulls. You did not power out in this video, you always spun out, so keep adding weight to the machines to find the max pull. You also should have the weights the same for both machines to accurately compare the systems directly. But in a nutshell you are showing with blocks, what we do in the Agriculture world!

[@GazRsExtremeBrickMachines]
