It would not be as the force required to rotate the last gear exceeds the maximum yield strength of the material the gear is made off. Meaning you would shear the teeth off the gear box before you could achieve any rotation.

@Dennis19901

Torque and RPM work proportional though. Torque does not in any way have anything to do with "energy exploits". If we assume that friction does not exist for a moment. If he would turn the last gear with some X torque, the output gear would turn with x / 65k torque. Albeit turning very fast, it has next to zero torque. That's also why heavy machinery doesn't go fast at all with massive amounts of wattage in their engines (a tank for example). It needs more torque and less rpm to be of any use.

If there was no friction at all, it would still require 65000 times as much torque; possibly more than the plastic gear can stand without breaking. But I'm likewise pretty sure that if you had all the time in the world and none of the friction, it would eventually get moving under otherwise reasonable conditions.

Yes, inertia may be the biggest factor here. Also, it is worth noting that speeds multiply by the same factor. If the last gear was spun so that it's outside moves at mere 1 cm/s, the first gear's outside would move at 650 m/s, almost twice the speed of sound.

What if you spin the first one, then when its momentum increases, you begin spinning the next one, and as the energy in the system continues to increase, you keep going up to the last gear? It seems to me like this would make things a lot easier.

i'm also printing them right now. One gear takes 1.30 hours. 0.4 nozzle, 0.2 layer height, 20% gyroid infill, 3 walls, outer wall 25mm/s, infill 55mm/s, inner wall 45mm/s

Very nice video

i like to think about this kind of scenario for how gravity 'causes' time dilation. moving through higher gravity is like moving the gears that are farther down the line in that machine- it means that the gears with 'less gravity' are moving at higher and higher rates - meaning that more time is passing for THEM while you are 'spinning' your gear at the same pace .

A guy told me one day "give me a lever long enough and I will move the world", a gave him a very long lever and he never came back.

this is actually really interesting, i wonder how you determine the factor by which it increases with each gear?

Relative diameters of interlocking gears when teeth are the same size. If you look, the gear teeth on the inner edge of one gear meshes with the gear teeth of the much larger outer edge of the next gear, so the first gear has to spin ~4 times to spin the next gear all the way around once. Circumference is a linear factor of diameter (pi * diameter), so the ratio between gears is linear relative to the size of the gears, and the factor is merely [diameter of next gear/diameter of current gear] when measured at the location at which the gears are meshed. In this case, the ring the outer teeth are set on is 4 times the diameter as that of the inner ring, so 4 times multiplier each set. Technically it is really the number of TEETH on each gear, but since the size of the teeth here are the same, it works out the same way: there are 4 times as many teeth on the outer ring as on the inner ring, so you get the same 4 times multiplier.

​@@Vertraic u cleared my doubt tnq

If there's one thing I know about gear ratio coming from Airsoft is that low ratio gears spin faster. I'm talking about Rita fire and the cyclic rate when they decide to make those upgrades people always bring up gear ratio. People rarely use high gear ratios anymore they just use high torque motors cuz you got to remember that it has to pull back a heavy spring to expel a projectile

What if like, the first gear is made out of steel to handle the force, then you attach a wrench or whatever to give leverage and you put that under a hydraulic press? The last gear would go nuts!!

At a certain amount of force, something will bend, break, or otherwise deform sooner than get that last gear spinning. In this case, I'd bet on the wrench bending or the housing for the gears deforming until a couple of the gears come uncoupled. After all, even steel can only handle so much force.

A googol amount of spins, KZread is owned by google. coincidence I think not

I've always thought about this and imagined what it would be like to do this

Lubrication is insanely important specially if you don't use bearings or proper bushings for the shaft

I know that it would've had no effect and it would've been a waste of time but you barely even tried to interact with the last gear. That is messing with my OCD.

Here is a solution start by moving each gear slowly and greatly move to the second gear each time making it easier for you.

This is good attachment for a Wimshurst Machine (electrostatic generator) in order to have more energy output with less effort to spin it.

Could you make something like this out of metal, then use an hydrualic press to turn one of the last gears? for instance, with a lever or somthing sticking out the last few gears. I'd love to see that
