How Slow can LEGO go? | Comparisons

My takeaway from this is that an ant (theoretically) could traverse the globe in less than 15 years time 🤯

Nice illustrations! Keep on going ! :-)

[@Indianawoodchuckjunior]

That is probably almost enough torque to pull a semi trailer if the parts could survive. XD

[@in1]

If the parts, connections and ground grip were infinitely strong, it would definitely be able to do that. Just very slowly.

[@buck45osu]

Medium motor has .12 Newton meters of force, 1 Newton can in a frictionless environment can move .225 pounds. A semi truck fully loaded can be 80,000lbs. 80,000lbs/.225= 355,555 newton's of force needed. 1.1bill x .12newtons of the motor is 132 million newton's. Or 371x the force needed.

It can move anything, just ad 1000, and i think u can move planets or stars but not practical at all...

[@vlastasusak5673]

When using worm gears, I've noticed they always have a little bit of play back and forth on the axle, like they're a tiny bit shorter than two units. That means when a worm gear spins, rather than transmitting torque right away, it has to screw itself up the spur gear maybe a millimeter, until it hits the barrier, and only then can it start driving the next pair. Given the exponential growth of the ratios, the amount of rotations needed to clear this gap also increases. Until every single worm reaches it's "locked up" position, the car can not start moving. How long would it take for the car to start moving in the extreme case where every single worm gear is as far back as possible from it's locked up position?

[@in1]

That problem should be fixed because I've used an axle with a stopper and the worm drive is pressed against that stopper using the 8 tooth gear. For the last few cars I just assumed there are "no tolerances"

[@Nebarus]

I built a similar setup, but without the motor, and it achieved a complete standstill. So very slow indeed! ;)

[@tronsl3014]

At 3:44 is a mistake. Light speed is 300 000 000 m/s if the speed in the box is correct it’s 20 times the speed of light and not only 2 times

[@in1]

You're totally right, I was pretty tired when I wrote those boxes. The image is correct, but both the gear ratio and speed have an extra "0"

[@tronsl3014]

@@in1 yeah all fine can happen I just thought when I saw the velocity looks little bit more like only two times 😂 if it would be possible to spin it that direction be careful not that universe explodes when you reach 20 times light speed 😂

[@Haxihoovis]

Hello, fello Randall Munroe fan!

[@Operator_Suerte]

so if you can go that slow and it would take a life time (most likely I would be near my death by it moves like a MM) so if it can do that why not reverse witch way the motor gets inputted meaning speed of light?

[@in1]

Interesting idea, but sadly there's a pretty simple reason why it doesn't work: Having an 8:1 reduction makes the output 8x as strong, but an 1:8 transmission reduces the strength 8x. In other words, there would be no force strong enough to power that car. Especially because screws are designed that they can't be driven backwards.

[@Terminarch]

Going into deep physics is not what I expected. I thought that you would calculate out the limit where these additive friction forces overcome torque.

[@in1]

In theory these forces should definitely be big enough, since every transmission 8x-es the strenght. It still wouldn't move anyways though, that's why I've purposefully ignored wear and "wiggle room" in the video.

[@villageblunder4787]

Please don't put text at the botto of the screen. You can't read it as covered by bloomin KZbin graphics.

[@in1]

Oh, that's a good point. But I guess that's also the case for the top, and I can't really put it into the center. Thanks for the feedback tho, I will try to put it a bit higher

[@Isasmrt2763]

I guess you could call this "how slow can LegGo?"

[@iamhugry]

This is not really true, when you are going to observe the end moving at the Planck length physics would break and you would see it moving forward or backwards or worse stuff as the laws of physics stop at Planck length

Thats a lot of torque, you should test how much it can pull.

[@in1]

That would probably simply make the wheel slip, axles bend or gears break

[@Drpaper1]

@@in1 oh

[@micahanglen4331]

@@in1 You could try making a super beefed up chasis and add some weight on it (to prevent the wheels from slipping) and see how much weight a single motor could pull with extremely high gear ratios.

[@mathieudevos9420]

This is so funny. I rarely comment on KZbin videos. I watch it on TV. I don't have the option to comment via my TV. But now I thought, let's tell Mr 2 in 1 Bricking that I like the music and that it has a Pavlovian effect on me. 😂😂 . But I do agree on the longer videos part. And maybe the duration of text information on screen could be a bit longer. Watching you building AND reading the text at the same time is not my strongest point.
