@marriott7863 3 года назад

torque seems like an added feature to stop easy energy exploits. smart of the devs to implement it!

@Dennis19901 3 года назад

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.

@roose1346 3 года назад

In theory, yes, but I think the construction would start vibrating and fall apart. Also the resistance would still be multiplied trough the gears so you would still need a lot of force

@AndyMooreMusic 3 года назад

@@roose1346 Yes, I think as constructed, it would turn into multiple spinning, flying, gears of death and destruction lol, but I like theories. If the entire system was brought up to speed slowly, the inertia of the system should eventually be such that the motion of the final gear could be maintained with relatively little force. The only road block I see is the first gear would probably be close to the speed of light.

A way I like to think about it after designing a few gear trains is as, as speed increases torque decreases. The power of a gear train is constant. For those who don’t know a gear trains purpose is to modify speed, or force but inevitably is going to do both.

@hbzandbergen 3 года назад

It's caused by the rotation inertia of the gears. For each couple of gears it is multiplied by (reduction)^2, giving the last gear an enormous inertia

@pauljs75 3 года назад

Friction also factors in as well.

@lilapela 3 года назад

I think Its inertia in combination with friction. if there was no friction, I assume it would be possibe to spin the last gear but it would take a long time to accelerate

@stickyfox 3 года назад

@@lilapela Each stage multiplies the total torque (friction + inertia) by the gear ratio. When run in the "normal" direction, the gear ratio helps overcome both friction and inertia. 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.

@pawelkusmierek109 3 года назад

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.

Would it be practical to jumpstart the last gear (or multiple gears) with a pull rope so that the resistance isn't so great? Btw I love your videos and you are amazing with breaking this all down!!!

Or not, by the time your wheel actually spins enough to get up there, you will have slid down again or died of old age 🤣

Man i miss my 3d printer. It broke down right before i moved and i didnt have space for it at the new place. Whenever i see one of these types of videos it reminds me all the cool stuff you can make with one

if the last gear spins very fast manually, the red gear’s going to spin more than hyperspeed, creating a space vortex

And maybe by shaping the first gear like a fan blade, you could create tornadoes ! 🌪🌪🌪🌪

I think it's more likely the mechanism would break

@aurilio5633 3 года назад

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!!

@peppermintgal4302 3 года назад

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.

If you spin up each gear individually moving up when it becomes easier you can spin the last one and make the first one go over 65,000 rpm

@ant_mk3596 3 года назад

This is cool, can you try using an air gun or something along those lines to try and turn the final gear and get some high speed cameras to record how fast the first gear is spinning?

What would happen if you put a similar but reversed gearbox (big wheel connecting to the big wheel) and spinn the motor. Will it just brake the connecting big wheels?

@rmpll 3 года назад

so now do a timelapse of spinning the gears until the last one does a full rotation :D

@SirPhysics 3 года назад

How long would that take? Let's do some quick maths. If he spun the first gear with a cordless drill, which typically gets 800 rpm, it would take just under 82 minutes for the last gear to make one full revolution.

That's all cool and stuff, but now I'm left wondering what you need a gear box with that kind of transmission for (except to help me understand the way my car works).
