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.

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

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....

Its crazy how quickly exponential returns can get unimaginably huge. A deck of cards is another example. The odds of shuffling a deck of cards and them returning to an order that any deck of cards has been in, is so small, it could be considered impossible considering the combinations made in the past and future. To give a visual understanding, if you were to begin writing the possible combinations on paper with each paper having a new combination, you would stack them up until they reach the moon, then pull a drop of water out of the ocean and start a new stack. When the ocean is dried up, refill it and destroy a single grain of sand. When all the sand is gone, the number of combinations you have gone through are still 10 zeros away from 1/8 the maximum number of combinations. The number of combinations looks like 8.0658*10^67 For a little more perspective, the universe has only existed for 4.36*10^17 seconds.

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.

I have calculated that if we move the gear at the rate of (299792458) per second at the speed of light from the begging of the universe (around 13.8 billion years ago there are still 7.648499 x 10¹⁴² years left to move the last gear once

You should try to make a clock using this gear ratio.
@stefanp42582 жыл бұрын
In such gearboxes you need to make gears and bearings stronger with each step, to convert high speed into more force instead. In your gearbox, the last gear has exactly same strength than first one, so it will break instant if you attach something heavy to it.

Well, if by "instantly" you mean after the heat death of the universe then.. sure.. It will be hundreds of billions of years before the last wheel moves, at all.
@stefanp42582 жыл бұрын
@@AndersHaalandverby But the nearly infinite force generated is already present at the last gearwheel, therefore nobody can turn it, without breaking 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.

Have you tried attaching a load to one side, and a generator to the other, for example, so that the load drops in 24 hours providing electricity? make a semblance of a gravitational power plant?

This is at least the third version of a "million year" gear train I've seen on YT. Most colorful version, though.

Try modeling this in Fusion with all the motion links and then try spinning the last wheel.

It is possible to get much greater rations with much fewer parts using "grinder gears" AKA "differential gears" Imagine two tubes with teeth on the inside. One tube has 100 teeth and the other has 101 teeth Imagine a cylinder 2/3rd the size of the tubes that has a step in its diameter. One part has 66 teeth and the other has 67 teeth. If you put the two tubes end to end, lock the 100 teeth on in place and then force the 50/51 tooth cylinder to roll around the inside, you get a ratio of 66/100 - 67/101 = -297:1 If you make more teeth or make the cylinder closer to the size of the tubes, you can get very big ratios. You can then cascade them like you did with the design you did to get huge ratios.

now we might have enough torque to open the pickle jar

just wondering, with "unlimited" budget, access to the best materials and machining tools, strongest and lowest resistance "aerospace grade" ceramic bearings, surface treated gears, axles, what would be the highest ratio/number of gears you could achieve that could be rotated from the slowest gears..I guess the best configuration would be using lightweight gears and lowest resistance for the fast spinning gears, and thicker/stronger/heavier gears/bearing for the slow spinning ones. I'm sure it would be quite amazing to see..this looks more like things I did with Lego technics when I was a kid.

Ignoring the laws of physics and just working with the numbers, if we were to assume the diameter of the gears are 16cm and the last gear is rotating at 1 RPM. The linear speed of the first gear would be approximately 1.006096*10^163 times faster than the speed of light in meters per second. Or 2.1744×10^82 mph

I guess if I get a Delorean and I put this gearbox into it, it's basically a real version of the "Back to the Future" one :o

I’ve done the math, and with your electric motor at 5300 rpm, it would take 3.589788x10^159 years to get the last gear to spin once. And for the last gear to spin within minutes, the first gear would need to spin at 10^170 rpm.

You could break the speed of light by simply taking the last wheel and turning it by hand. By running it backwards, each wheel would turn ten times faster...

What if you got a million people to crank a lever that’s attached to the final gear. Lol just my imagination being weird again
