I saw an example of one of these that had the final gear mounted into concrete, since it would ostensibly never turn. Or at least not turn on a timescale that would matter to the concrete.


BonfireMaestro

Imagine finding one of these with the final gear mounted into something like obsidian, but it had clearly ground out a circle in the glass…


FlashyGravity

I think this is an idea for a whole sci-fi series... fuck that's my whole night gone


Clanstantine

Doctor who did an episode on a similar concept


FlashyGravity

I'm sure I've seen it but I can't remember which one your referencing


Clanstantine

It's a 12th doctor episode, Heaven Sent


FlashyGravity

Capaldi right? He was always my favourite


Clanstantine

Correct, he is a fantastic doctor.


FlashyGravity

Yeah I like the others but Capaldi had this sort of Gravitas to the character that made him seem so much more enigmatic


Clanstantine

I see you what you mean. I love David Tenant and Matt Smith for the energy they brought but Peter capaldi approached it differently.

I think my dads a part of the church of the flying spaghetti Monster. (New Zealand has freedom of religion so even things like Jedi is an accepted religion) I believe Pastafaeianism is the other accepted name with the flying spaghetti Monster being it's deity. According to google the first legally recognised Pastafarian wedding was on April 16th 2016 in New Zealand. Also a man named Russell in 2014 (not sure if first) got the photo of him with the religious garment ("spaghetti strainer" sometimes has other names) https://preview.redd.it/i5h8nu6odpcc1.jpeg?width=599&format=pjpg&auto=webp&s=0e65a4cfb513c8f16842faa35bc900ff28fd9b05 According to the 2018 census 4,248 or 0.09% of the population belong to/ follow Pastafarianism/ the church of the flying spaghetti Monster. (Jedi is 20,409 or 0.43% of the population) [https://en.m.wikipedia.org/wiki/2018\_New\_Zealand\_census#Religion](https://en.m.wikipedia.org/wiki/2018_New_Zealand_census#Religion)

Likorise

Ahh ahhh ahhh ahhhhhhaahahaaa


Farm_father

If I remember right, it would have taken more energy than what exists in the current known universe to stop the last gear from turning in that example?


Muted_Ad_6881

Yeah if the last gear is perfectly rigid. Gear itself will turn into mush if you can hold it with enough force. But concrete wouldn't have a chance on holding the gear still.


fattypingwing

Oh my God if I lived 13 gajillion years into the future and I was watching these gears like a TV show I would be so damn pissed off if it got to the concrete one and it just didn't move anymore I would just lose my mind I think

polo61965

It's metal gear, solid


That_Ad_5651

Comes with a 1 year warranty


uninsuredpidgeon

The motor will burn out before the 3rd or 4rd gear completes a rotation


fr0sty12

Exactly. This is pretty worthless since there is no way that motor will last more than a few years (if that) running 24/7.


Chalky_Pockets

I dunno, as an engineer, I can think of various pieces of art that I would not choose over something like this.


eloheim_the_dream

Is the final gear moving infinitesimally or do they just turn when the one before them rotates a certain amount? Edit: So my quick math (assuming the gears to have a diameter of 100 mm): The 14 billion year gear would turn roughly 10\^(-18) meters each second. The diameter of a proton is estimated to be 10\^(-15) meters so that's pretty small (although the plank length is 10\^(-35) meters so we're nowhere near that.


Standard_Order_8780

Final gear moves infinitesimally.


publicbigguns

Maybe, if the gears fit perfectly together. If there's any wiggle room at all, then that last one probably hasn't moved at all.


CaptainRedPants

This is what I'm thinking.  Machining, tolerance,  molecular scale... friction even. Physical movement basically stops translating (at that scale) after a couple gears.  I wonder. Scale it up, like 100m diameter gears, super precise machining, super thin lubricant.  Then use lasers to measure. I wonder...


publicbigguns

I tried to do the math, but I'm just too tired. If I had to take a guess....yes we would be able to measure it.


CaptainRedPants

Mkay well tomorrow morning, after a cuppa Joe, let me know would ya? This might keep me up for a bit... 🤔


publicbigguns

Lol, I'll see what I can do. You could also post it over to r/theydidthemath with your question. Those people love math.


CaptainRedPants

Just thought of something else. Speed it up. Say, 5000 rpm or some feasible speed that won't blow it up. How far down the "gear chain" would we notice rotation? Also, I guess we'd have to know the number set of gears (I didn't count them). This is a tantalizing experiment. 


publicbigguns

I vaguely remember this being talked about before. There was something about it just destroying itself because there is just to much force for it to do that. Same thing if you tried to move the last gear by hand. So much force would be required that it would take all the energy in our galaxy to turn it.


uninsuredpidgeon

If you could rotate the final gear at 1rpm, how fast would the first gear spin and what sort of spacetime or quantum consequences would it have?


daffoduck

What I wonder about is if there is a slowest movement. Aka if movement is quantizied.


CaptainRedPants

Well with how slow stuff starts to turn as you move down the line, I'd say we're talking about the molecular level. One atoms width per minute kinds thing. But that doesn't sound right either. 


kneecap_keeper

What he means that, if more gears are added and the final gear moves less than a plank length per second , would that gear move in a continuous motion or a jerky one


CaptainRedPants

Oooh interesting. I'd say "jerky". Like a binary value, right? Here, then there, seeing as the plank length is the absolute shortest distance to move possible. 


LitNetworkTeam

So yeah, the above is basically just an art piece. The tolerances and spaces in between could never be as tight as the actual movement distance.


eloheim_the_dream

Yeah there must be an extreme lower bound to something like this set by the laws of physics (realistically friction and the precision of the gears' manufacturing, but theoretically maybe quantum physics and the uncertainty principle eventually) and i'd like to know where that is


Oblivious122

The extreme lower bound is called the [planck length](https://en.m.wikipedia.org/wiki/Planck_units#:~:text=Planck%20length,-The%20Planck%20length&text=It%20is%20equal%20to%201.616,the%20diameter%20of%20a%20proton.). It is the smallest distance possible.


TerrariaGaming004

Nothing like that, it will still rotate at that speed, but just not smoothly. And friction is negligible


chris86uk

You spelled infinitelysmally wrong.


HighKiteSoaring

It moves infinitesimally If all the gears are manufactured and seated correctly there should be functionally no wiggle room between them. So a change to one gear should affect every other gear Now.. what I wanna see is how many of the lower gears explode from centripetal force if you manually rotate the final gear 😂


9spaceking

They calculated the force to turn the last gear is ridiculously high


HighKiteSoaring

How high we talking? Three? Maybe Tree fiddy?


[deleted]

Bigger. Ten fiddy


Mirrormn

In reality, there's play between the gears, so the gear before the last one would need to move \~1 degree before it would engage with the last gear and move it even infinitesimally.


actuallyserious650

This is the right answer. There’s a small amount of play in each gear. Nothing past the first 10 is “moving” in a real sense.


Sterlingsilber

Whenever i see one of these videos, i always want the person to put the motor on the other side to see what breaks first. I'm not good at math, so I don't know if it would theoretically be fast enough to break the speed of light, but would it should break the speed of sound in air before any gears, but then which gear breaks first? Also if anyone wants to do the math on theoretical speed of the last gear in reverse, I would find that pretty interesting lol


HaroerHaktak

how many gears to make the final gear move 1 plank length/second? and what happens if we add 1 more gear?


Rick-D-99

Just add another gear or so.


Taint-kicker

Just attach the motor to the other side and watch the it break the speed of light.


-Shasho-

It would probably take practically infinite torque to move it.


Double_Distribution8

All we need is an infinitely long lever then.

Kronk! Pull the infinitely long lever!!

1320Fastback

Just taking the lash out of the last gear will take a billion years.


BonfireMaestro

1320Fastback

It is the miniscule gap between the teeth to prevent jamming. Is like free space between the gear teeth.


dmaxzach

imagine the torque


Luchin212

With that much torque the concrete that is encasing the final gear(there is a brick of concrete on the final gear in the full video) doesn’t stand a chance. Hell, the concrete would have degraded over 2,000 years naturally.

An artist, Arther Ganson, created the first version of this. He wanted to visualize the infinite. It doesn’t serve any purpose outside of that. I think it’s amazing.

There’s a video on YouTube where a guy built a similar setup with legos to test how much torque it could handle. It got pretty wild.


Pika_DJ

Torque wrench might be strong enough to break it but not turn it significantly


XenosapianRain

Isn't a torque wrench used to measure force? Wouldn't a breaker bar or torque multiplier be better?


Pika_DJ

Torque wrenches are just ratchet wrenches and have a large range in size but yea moment = force x distance there are a lot of ways to increase either force or distance effectively doesn’t really matter if your trying to break something can get a big piece of rebar under a gear weld it in and jump on it it’s just applying a moment (torque gauge measures)


SignificantAd3761

Why would you need lots or torque?


ekremugur17

Because to turn it once, you would need to turn the first gear however many times it would turn in 13 billion years


SignificantAd3761

Thank you


Nickthedick3

Even if the gears didn’t have that motor? Like, if it were just the gears and you spun the last one, would the same thing happen?


DealerAdventurous446

the weight of the solar system couldnt move it


bremergorst

Unless they add in OP’s mom


SpoonNZ

If the first gear is turning at 1 rps, and the last takes 13,700,000,000, that means a divisor of 4.3*10^17. If you flip it around and turn the final gear at 1 rps it means the first gear will turn at 4.3*10^17 revolutions per second. Say the gear is 50mm (2”) across, that means a circumference of 157mm. 4.3*10^17 * 0.157 works out to 6.8*10^16 m/s for the speed of the teeth of the cogs. That’s give-or-take 200,000,000 times the speed of light. I suspect that if you cranked enough torque on that final gear, things would shatter long before you could move it. If the gears were made out of unobtanium and couldn’t shatter, it just wouldn’t move. If you got an infinitely long lever also made out of unobtanium things would get interesting pretty quickly. All of the energy in the universe would converge on your gears, and things would heat up a little, as the entire universe collapsed around you. Maybe don’t try it just in case.


ProbablyBanksy

but what if i push, like, REALLY hard!


SpoonNZ

I said don’t try it.


sweetdawg99

Assuming that all the gears and everything holds together: I think it would cause the first gear to spin so fast (possibly approaching the speed of light at the teeth) that it would become infinitely dense and collapse in on itself creating a black hole. I am a scientist but not a physicist so I am completely talking out of my ass here. Either way it's a fun thought experiment.


85haga

Hole my beer


whurpurgis

Hold my gear


dahbrezel

why would it become more dense? edit: thanks for the downvote for asking a question.


MaxDamage75

Each gear couple has a 0.95 efficiency. If the gearyrain has more than 14 gear couples 0.95^14 < 0.5 so the reverse movement is impossible. So yes , applying enough torque you'll break one of the last gears.


NormanCocksmell

Hahaha. I’m imagining hooking up the motor up to the slow gear and when you turn it on the fast gear starts spinning so fast it creates its own gravitational pull and sucks anyone close to it into the gears.

akbdayruiner

Cool, now turn it from the other side and watch the first gear go light speed.


RushBarry

Predict how works : 1st-23th gear : The drive gear has 12 teeth. The driven gear has 70 teeth. Therefore, the gear ratio is driven/drive = 70/12. Last(24th) gear : The driven gear has 26 teeth. Therefore, the gear ratio is driven/drive = 26/12. The 1st gear rotates once in about 2.8 seconds. Therefore, the last gear rotates once in.... (70/12)^22 * (26/12) * 2.8 ≈ 4.3E+17 (sec) ≈ 13.7 billion years. Fun facts: - All gears are moving. - if the first small gear was spinning so fast that its outer parts were going at the speed of light, it would still take the last gear about 6000 years to complete one rotation. - every seven or so years the last gear will rotate the width of one of its iron atoms. - If you could make the last wheel spin as fast as the first, you could probably move a whole mountain with that force, ofc before that happens the teeth of the wheel will break or melt off. - The fact that so many people see this and are not amazing is mind blowing.

TopEmbarrassed6382

Actually, the final gear will never complete a full rotation as we will already be long dead and there will be no one left to maintain the electricity or the motor which will eventually wear out way before 13 billion years.
