Did some rough estimations, and calculated that 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. Also, in theory, currently every seven or so years the last gear will rotate the width of one of its iron atoms.

Not true. Naturally there is material inconsistency and a limit to the precision of these gears. As you progress down the chain to slower speeds, even the slightest imperfection is dramatic. It is safe to assume that quite a few of the end gears are in fact not actually spinning. Granted if this system could run without wear, eventually, many many years later the tail end gears would make first contact
I made a calculation. If we run the motor for 38 years straight without a gap, the last gear will turn be a whopping 1/1,000,000° (one millionth of a degree).
It won’t turn at all, several gear before that aren’t turning at all either. There is backlash/play in the gears, where the tooth is just in empty space not touching the next gear, and you have to wait for that tooth to meet the other tooth to push the next gear.
lol, that's exactly what IS happening. The last gear is partially encased in cement so it can't rotate. You'll "behold the big bang" when the mechanism blows up at some point in the future, but that's likely to be after at least a billion or so years.
@Quinton Baker Theoreticly it WILL take ALL the energy in the universe, simply Because of the required Number of turns of the wheels. Of course it Will wear and tear long before.
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.
Japanese translation: 最後段１回転１３７億年を検証。１～２３番目のギアにおけるドライブ側の歯数は１２枚、ドリブン側が７０枚なので１ギア当たりの減速比は70/12=5.83。最後のギア(２４番目)におけるドリブン側の歯数は２６枚なので減速比は26/12=2.17。よって総合減速比は(5.83^22)*2.17=1.54E+17。最初のギア(１番目)が１回転約２.８秒なので最後のギアの１回転は(1.54E+17)*2.8 ≈ 4.3E+17(sec)。これはおよそ１３７億年。
At first I thought “wait that concrete block at the end might have too much friction and stop the gear from spinning” then I remembered that’s in the *other* direction and that gear could move a skyscraper

It's actually not spinning at all due to physical limitations; the gears would need to have perfect traction (and also be indestructible) in order for the last wheel to budge even an infinitesimal amount.
Fun fact: 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.
Mountain? There is not even the amount of energy in the entire universe that can make the last wheel spin as fast as the first, and the first would be spinning many times faster than light.

So you are saying those spaces between the teeth (backlash?) prevents them from responding immediately hence if you add them all up in a gear system with googol teeth it becomes an infinite spacing?
@@BongelaMnguni You are complicating simple concept with this "googol middle gear" alot :D. let say one teeth weighs 1 gram, this googol gear will weight 10^97 kg, more than entire universe (10^53)kg , and surface area between 1st and 2nd gear will have to be able to wistand force that will move mass of entire universe. so in reality what will happen is :1st - it will not move at all, 2nd. something will break in first gear (tooth or motor will burn) or 3rd. this googol gear will colapse into itself and form biggest black hole in universe.
So if the gears were perfectly meshed with no play what so ever the last gear would be moving of course imperceptibly slow. The last gear is probably not moving in a smooth motion due to tolerance stack up between the gears.
@@sinisterdeer7601 So when I was talking about a perfect gear mesh I was talking about multiple gears in a train, not two gears alone. However, yes if you could achieve no play in a gear train then the output gear would move some small finite amount for a given rotation of the input gear no matter what the gear ratio. To your question smooth motion is a function of play and gear engagement. Involute gear teeth roll over each other without sliding. With straight cut gears there may be some step in power transmission as the individual teeth engage and disengage. If the teeth could be cut perfectly and stay that way then the power transmission would be smoother. Most modern gear trains use angle cut gear teeth so that between any two gears some teeth are always in contact. That greatly smooths power transmission.
I want to see this machine but with these I’ve on the other side. I’d have multiple clutches, fly wheels, balanced gears, and high speed motors. The idea would be that each “set” would be independently spun up in order. First sets spins up to rpm, then the flywheel activates and keeps the gears running, while the next set spins up until it reaches right rpm to engage with the first set. That process will repeat until either the gears shatter or the universe collapses.
funny thing is you could weld the last gear solid and it could still run for years, there isn't even enough movement to take the slack out of all the gears.
torque^100 technically. Not even a googolplex yet, which is a 10^googol or 10^(10^100) All things considered, in our mind, it might as well be infinite.. but our minds can't fathom a googolplex, let alone infinity.
would love to see what happpens after a while and all the gaps have been filled and the power is going through them all. it would probably break the concrete
@@Sphere723 But first the axle would twist (deform) for a couple million years. Even if they removed all slack at assembly and the last gear was actually moving from the start, it wouldn't matter.
@@user-xg8yy7yl1d Tourque is not the issue. And gas/diesel engines don't produce that much torque. I've wrenched nuts to 1400Nm by hand with a 2m torque wrench. The issue is the friction inside the Transmission. You have to produce SO MUCH torque, just to overcome the friction of the gears, that the First gear CAN NOT handle the force and will break. If you slowly add torque to the last gear with an electric motor, it will go from nothing happens to BOOM, the gear breaks. Say you have an internal combustion engine that produces enough torque so that in theory you could overcome the friction, you'd have a transmission in front of it and a clutch connected to the gear. You'd rev the engine up to speed, say 7000 rpm, and then engage the clutch. And BOOM, the gear breaks.
Not to mention that if you could hypothetically get the last gear to move, the first gears perimeters would be accelerated beyond the speed of light. Which obviously is impossible. The weight of physics itself would hold it back. Unless, of course, you had infinite energy.
@Le scenette dello Zoo di 105 just ignore all aspects of resistance in the physical world and try to calculate the reverse ratios of the gears, that's all I'm wondering... Because I'm too lazy to do the work myself. (Edit: spelled resistance wrong)
How menny degrees will the square need to move in the concrete till it fractures? Kuz the way I see it if 360 Degrees is 13.7bil years then just devide it into into 360 and whatever the number is that will be 1 degree. Now to figure out how many it will take to fracture?
1 degree will take 38,055,556.6 YEARS! AND THATS NOT INCLUDING THE SLACK!👁👄👁 Now I wanna make one that has less gears and make it 1:2 ratio so it will crack it in like Idk 25 or 50 years lol
Concrete can actually undergo quite a bit of creep deformation, I don't think it's entirely clear if the concrete would fracture at all or instead plastically flow around the gear teeth. Sounds crazy, I know, but I think over the span of millions of years, the concrete would behave like fluid, not a solid.
Wait but couldnt you use it like gears and spin the first which makes it easier to spin the second and then spin the second which makes the third easier and go on till the last one
If, instead of the concrete block at the end you continued to add gears, but instead of continuing with increasing the torque you started to decreased it, so that now the whole contraption is double the length, but now the last cog is moving the same speed as the very first one. Would that work?
In theory, yes, in reality, no. If you consider just the second half of your idea, the torque reduction from the slowest gear to the output gear is going to be ridiculous. So even if you assume that each gear only has a tiny bit of friction , you're going to require *enormous* torque to overcome this friction at the input. Basically, there's not likely to be any material which could survive without stripping the gear. The gear train kinda similar to a worm drive - it's not really possible to back-drive in practice.

I want to see this machine but with these I’ve on the other side. I’d have multiple clutches, fly wheels, balanced gears, and high speed motors. The idea would be that each “set” would be independently spun up in order. First sets spins up to rpm, then the flywheel activates and keeps the gears running, while the next set spins up until it reaches right rpm to engage with the first set. That process will repeat until either the gears shatter or the universe collapses.
the gears shatter
I wanna know, if you try to twist the last gear hard, will the motor speed up/slow down?
I want someone to spin the last gear and see how fast the first gear will go
The amount of torque it would take to move the last gear it mind numbing.
@@cjpaish you can tap it and it would move
@@kleonymos5726 No it wouldn't lol.
funny thing is you could weld the last gear solid and it could still run for years, there isn't even enough movement to take the slack out of all the gears.
its literrally encased in concrete.
I just curious, if you had enough force to turn the last wheel quickly, how fast would the other cog move???
It would break the universe if it was strong enough to withstand that much speed, we're talking infinite numbers
what force is needed to turn these gears using the force at the exit
alternate title: how to measure a Planck length
torque: *[infinity]*
torque^100 technically. Not even a googolplex yet, which is a 10^googol or 10^(10^100) All things considered, in our mind, it might as well be infinite.. but our minds can't fathom a googolplex, let alone infinity.
@@shadowproductions969 our brains would melt trying to understand the numbers , there is not enough space to stock all the numbers in our brains :D
@@TheTrooperMB or in the known universe according to numerology. All the atoms in the universe don't even approach a googol. It's crazy
I wonder if we connect a car engine to the other side would it move? If not what if we try it with a gearbox connected to the engine
Wow! 😲 That's a long lasting motor- mine always breaks down after a couple of years...
i was looking for this comment, no man made motor will last 13.7 billion years especially nonstop.
Just remove all the in between gears and connect the last year directly to the first one. Problem solved!😜
That’s what I thought! Bypass the plan 😆
I've done the calculations, I'm pretty sure 1+1=2.
What are the gear ratios?
It's been 8 years, how many gears have turned at this point, any update to this video?
would love to see what happpens after a while and all the gaps have been filled and the power is going through them all. it would probably break the concrete
No, they'd just spin slowly. They're on bearings after all
Concrete can undergo substantial creep deformation, the gear couldn't spin faster than the concrete could plastically deform.
@@Sphere723 But first the axle would twist (deform) for a couple million years. Even if they removed all slack at assembly and the last gear was actually moving from the start, it wouldn't matter.
Now spin it on the other side and watch it go into warp speed. Ifu can find a strong enough motor
dnh300 if you try to spin it from another side it will take so much force that the last gear will just break
@@adaptablerubenvideos3097
Couldnt a high torque gas motor handle it?
@@user-xg8yy7yl1d Tourque is not the issue. And gas/diesel engines don't produce that much torque. I've wrenched nuts to 1400Nm by hand with a 2m torque wrench. The issue is the friction inside the Transmission. You have to produce SO MUCH torque, just to overcome the friction of the gears, that the First gear CAN NOT handle the force and will break. If you slowly add torque to the last gear with an electric motor, it will go from nothing happens to BOOM, the gear breaks. Say you have an internal combustion engine that produces enough torque so that in theory you could overcome the friction, you'd have a transmission in front of it and a clutch connected to the gear. You'd rev the engine up to speed, say 7000 rpm, and then engage the clutch. And BOOM, the gear breaks.
Not to mention that if you could hypothetically get the last gear to move, the first gears perimeters would be accelerated beyond the speed of light. Which obviously is impossible. The weight of physics itself would hold it back. Unless, of course, you had infinite energy.
What happens when you rotate the wheel by hand? Does it make a black hole or what?
When the last wheel does eventually turn, make a video showing us what happens to the concrete. I would be quite interested to see that.
Bud, ya wont be alive
we would die before it does
I'd like to think that if a blackout happened they'd have to add a couple thousands of years
“Theoretically”
It will warm and creep before the "bigbang"...
I wonder how much torque would be needed to spin it from the opposite end
What if we put motors on both the two ends spinning in opposite directions?
you can't put a motor on the other end because it would require more energy than the entire universe has to offer!
WHO ARE THE 73 PEOPLE THAT DISLIKED THIS VIDEO, WHY WOULD SOMEONE EVEN DO THAT
Science “We should be conserving energy for important things!!”
Also science:
I saw that gear in a museum. I think it was in boston.
So if you manually crank the last gear how fast would the first gear spin?
j l I would also like to know the torque requirement. That’s a mathematical calculation that would hurt an iPhones calculator apps feelings.
@Le scenette dello Zoo di 105 just ignore all aspects of resistance in the physical world and try to calculate the reverse ratios of the gears, that's all I'm wondering...
Because I'm too lazy to do the work myself.
(Edit: spelled resistance wrong)
That's highly inefficient
See y'all in 13.7 billion years later when the last gear rotates.
How menny degrees will the square need to move in the concrete till it fractures? Kuz the way I see it if 360 Degrees is 13.7bil years then just devide it into into 360 and whatever the number is that will be 1 degree. Now to figure out how many it will take to fracture?
1 degree will take 38,055,556.6 YEARS! AND THATS NOT INCLUDING THE SLACK!👁👄👁
Now I wanna make one that has less gears and make it 1:2 ratio so it will crack it in like Idk 25 or 50 years lol
Concrete can actually undergo quite a bit of creep deformation, I don't think it's entirely clear if the concrete would fracture at all or instead plastically flow around the gear teeth. Sounds crazy, I know, but I think over the span of millions of years, the concrete would behave like fluid, not a solid.
Fun fact: The last gear has been encased in concrete to prevent somebody accidentally spinning it and causing a black hole to emerge at the other end.
So if we turn the motor to the last gear, would the first gear be moving like at light speed?
You cant possibly get s motor with that much Torque, it just isnt gonna happen
Wait but couldnt you use it like gears and spin the first which makes it easier to spin the second and then spin the second which makes the third easier and go on till the last one
Hope they’ve got a lot of blinker fluid
If, instead of the concrete block at the end you continued to add gears, but instead of continuing with increasing the torque you started to decreased it, so that now the whole contraption is double the length, but now the last cog is moving the same speed as the very first one. Would that work?
In theory, yes, in reality, no.
If you consider just the second half of your idea, the torque reduction from the slowest gear to the output gear is going to be ridiculous. So even if you assume that each gear only has a tiny bit of friction , you're going to require *enormous* torque to overcome this friction at the input. Basically, there's not likely to be any material which could survive without stripping the gear.
The gear train kinda similar to a worm drive - it's not really possible to back-drive in practice.
