World's biggest gear ratio...

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.

[@knownas2017]

That sounds kinda cool, tbh.

[@saisubdivision3941]

Imagine aliens coming upon this wall that is slightly tilted by a fraction of a centimeter in the future

[@zenith1047]

For those interested, I've found the piece: it's called "Beholding the Big Bang" and it's a bit different than what I recalled (it has been years since I've been to that museum and seen the exhibit). The final gear is embedded in concrete, not carved out of stone, and it's an electric motor turning the first gears, not a hand crank. kzbin.info/www/bejne/jHSkY6qepbJ2pNE

the mechanical flex of all the gears probably compounds up

[@baguette1014]

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

[@matthewmaillette]

The whole thing would explode but it would be glorious

[@Godolotl]

Assuming the gears were indestructible and you could apply infinite force, if you spun the last gear, the first gear would be moving far faster than the speed of light

[@baconwizard]

@@Godolotl but as you approached closer to the speed of light, from the gears perspective, time would be slowing down which would inadvertently slow down the rotational speed of the last gear who’s torque is probably enough to lift up the whole universe.

[@Godolotl]

@@baconwizard well yes, but this whole thing is irrational to begin with. I mean that gear ratio is just a "because I can" thing. If you actually could apply infinite force, I'm unsure if you could ever actually reach the speed of light due to time dilation. On the outside it would appear close to the speed of light, but from the 'gear's perspective' everything would speed up. This weird dynamic is why the "speed of light" is so odd.

Lets do some mafhs assuming all the gears have zero mass. So.. light wave can go 186000 miles or 299337.984 km in a single second, now if each teeth of the gear is more or less 3 milimeter in base width, then the circumference of the gear is 36 cm = 0.00036 km. Thus if the gear is spinning at the speed of light then in 1 second, it will rotate roughly (299337.984 ÷ 0.00036) = *831,494,400* times.. now heat death of universe occurs after 1.7^106 years or 8.44656945×10^31 seconds so to make the last gear spin 1 time before the heat death of the universe, the first gear has to spin 10^169 times within this time period, so as each second passes the *first* gear would have to spin 10^169 ÷ 8.44656945×10^31 ≈ *1.2 × 10^199* times. If u want the rpm then we just gotta multiply this by 60 ≈ *7.1 × 10^200* RPM. How many times faster is this rpm than the speed of light? Just divide the rps (s for second) of the gear if it had to finish rotating before the heat death of universe, by the rps if it was rotating at the speed of light. That is, 1.2 × 10^199 ÷ 831,494,400 ≈ *144 × 10^188* times faster than the speed of light....

[@ShayminLover492]

So let's get this into perspective: Let's assume the first gear rotates at 1 revolution per second. At that pace, it would take 10 seconds to spin the 2nd gear by one revolution. The 3rd gear would take 100 seconds, or just over a minute and a half. The 4th gear would take 1,000 seconds, or just over 16 and a half minutes. The 5th gear would take 10,000 seconds, or just over two and a half hours, and so on. Once you reach the 6th gear, it's already gonna take over a day to rotate it, and the 8th gear will take nearly four months to spin. Spinning the 9th gear will take just over three years, and you won't even live to see the 11th gear make one full rotation since it will take just over three centuries to fully spin. By the time the 17th gear fully rotates, the solar system will have completed one orbit around the Milky Way, and the next supercontinent, Pangaea Ultima, will have formed. The sun won't survive to see the 19th gear spin, since it will have died and become a white dwarf long before then. For the 170th and final gear to rotate, it would take 3.169x10^169 years. What if we worked the other way? How fast would the first gear spin if you managed to rotate the last one. Firstly, assuming that it takes 30 g to spin the 1st gear, it would take 300 g to spin the 2nd gear. To spin the last gear would require 3x10^170 g (3x10^167 kg), over 3x the weight of the entire universe, which means you would literally have to channel the power of the multiverse to spin that last gear. Now let's talk about speed. Assuming a radius of 20 cm, that would lead to a circumference of about 63 cm. The 1st gear would spin at 0.63 m/s (2.27 km/h, 1.42 mph), and the 2nd gear would spin at 6.3 m/s (22.68 km/h, 14.18 mph), and so on. The last gear would theoretically end up spinning at 6.3x10^168 m/s, or 2.268x10^169 km/h. Considering that the speed of light is roughly 300 million m/s, or 1.08 billion km/h, this last gear would be spinning at well beyond the speed of light, completely destroying the very laws of physics that we're operating by.

At what rpm is the first gear being turned to take 25k years. How many time does the first gear need to turn to make the last move 1 time.

[@the213don]

So did you increase the number of teeth for each gear related to the next gear? and what is the number of teeth on the last gear?

Great channel. I just joined up. Here are some thoughts I'd like to bounce off the community. I bought an Ender 3 last year so I could build things with my 5 yo son. Namely, I want to build gear ratio and mechanical motion demonstrators--which is a perfect fit here. I had pondered using Lego Technic. But I don't have that sort of budget. Your channel seems to solve that problem, with a 3D printer at hand, at least. And I'll admit I mostly don't want to get into designing actual gears. Done properly, that's an endeavor I just don't have time for. But I do have time to design drivetrains from a known set of gears. And that's where I want to spend my time on this project with my son. It will be up to him to take it to deeper design territory. I'd love to get into any efforts along these lines with anyone who wants to or is already doing projects with their kids. Thanks all, Tim

If the last one gear move the first gear world be 100000000000000x faster than speed of light

Do u trying to silander to rotatet to this gear s tam to time travel bcz ratat ligh speed if ratate last weel ithink u just do it 1 sielander to joint last weel to make speed just try
