There's something like this at the MIT museum (or at least it was a piece there when I last visited): a gear train with massive reduction and the final gear is actually carved out of the stone that it is mounted to. It's impossible for the final gear to move, but the beginning wheels are still able to be turned.
-
Damn just imagine the amount of force you would need to spin the last gear by hand and how fast it would make the first gear spin if you spun it from the last gear
-
You can't spin the last gear, but what gear can you spin from to maximize speed of the first gear?
-
2:50 It's even hard to understand how MUCH BIGGER this number is. If EVERY atom in the observable universe had its OWN observable universe within it with the same amount of atoms, then the number of all the atoms COMBINED would've still be a HUNRDED THOUSAND times smaller than this gear ratio!
-
I never thought I’d ever experience cosmic horror from such a small object
-
Last one will still prolly still make a revolution before GTA 6 is released...
-
It would be cool to see a gearbox like this but with 2:1 gear ratios so we can see it actually working.
-
The last wheel cant actually spin right?
-
Crazy thing is, if you could spin the first gear at an infinite rpm, the last gear would spin at infinite rpm too
-
I'm working on my own insane gearbox using planetary and grinder gears to achieve a ridiculous 500:1 gear reduction per stage. It will only need 63 stages to pass your gearbox. The crazy thing is that the design has an extremely small profile with a thickness of just .25in per stage and an external radius of 5in. The total length of the gearbox will be just under 16 inches
-
This is actually mindblowing! It must have taken a whole lot of time to make this video as well. Amazing!
-
Try to move the last gear if you can, the rest of the gears will rotate at fantastic speeds
-
Great video. Too bad you didn't include digits 0 to 9 embossed on each gear as you printed them. Then you could see how many revolutions of the first gear have occurred. Can you imagine the torque that could theoretically be put on that final gear.
-
I wonder how astronomical the torque would be on that last gear. Probably enough to move the world in theory.
-
I would love to see how fast the first gear would spin if it was possible to spin the last!
-
That's cool and all, but actually it is more than likely that friction will cause a good chunk of the gear box to never move at all, and rotating the first gear for long enough will cause some of the gears to simply snap.
-
Another video in my life of things I don't understand but still very intrigued and interested in.
-
If you somehow got enough energy and force to spin the last gear, then you would open up a wormhole at the other end because it would go faster than the speed of light.

03NOV2022 - Back in the 1950-60s near Columbia, Tennessee, you could stop on the highway and see "Bullwinkle's Geared Monstrosity." It was made of pulleys and v-belts. Somewhere I still have a postcard from that. I've always wondered what happened to it.
-
Something that is weird to think about is just how small the movement per second is...because if the high speed end is moving then the low speed one is too just so slowly you probably cant even see it under an electron microscope.
