it can't turn at the speed of light
and the gears would break before either even got close
>>703550338
What if they are made of diamond?
>>703549939
nothing
it would lack all mass and therefore would lack the necessary force to push said gear.
>>703549939
Then wheel two moves faster then the speed of light, since it movrs faster then wheel one.
>>703550401
what about vibranium
>>703550338
>>703550401
not even if it was made by your mom's crystalized tears when i fucked her last night would it survive the friction
>>703549939
as long as the gears are made out case hardened diamond it shouldn't be a problem
>>703550338
This
>>703549939
They would both explode.
>>703549939
This is obviously bate, but for those who don't know, the gears will move at the same speed, just since one is smaller the teeth have less distance to travel, so it's teeth will make a full rotation faster, but the teeth will have the same speed as the bigger gear's teeth
>>703549939
Friction doesn't allow. The small gear could turn that fast, but the big one won't be able to.
>>703550510
Tears are the best lube, aren't they?
>therez a way!
>>703550513
Only if the hardened diamond is made out of other, slightly harder hardened diamond.
1: Nothing can travel at the speed of light. Only light has that capability.
2: It gear 1 was turning near the speed of light, it would either break the other gear(if it instantly accelerated to that speed) or they would bot melt due to friction with the particles in the air (if it gradually accelerated to that speed).
Super simple
>>703550648
>full rotation faster
>same speed
pick one
>>703549939
no matter with mass can travel at the speed of light
If gear 1 turns at any appreciable fraction of the speed of light, let's say 0.1c, both gear will stop being gear and star being hot plasma and gamma rays
What would happen if you tried to hit a baseball pitched at 90% the speed of light?
Let’s set aside the question of how we got the baseball moving that fast. We'll suppose it's a normal pitch, except in the instant the pitcher releases the ball, it magically accelerates to 0.9c. From that point onward, everything proceeds according to normal physics.
The answer turns out to be “a lot of things”, and they all happen very quickly, and it doesn’t end well for the batter (or the pitcher). I sat down with some physics books, a Nolan Ryan action figure, and a bunch of videotapes of nuclear tests and tried to sort it all out. What follows is my best guess at a nanosecond-by-nanosecond portrait:
The ball is going so fast that everything else is practically stationary. Even the molecules in the air are stationary. Air molecules vibrate back and forth at a few hundred miles per hour, but the ball is moving through them at 600 million miles per hour. This means that as far as the ball is concerned, they’re just hanging there, frozen.
The ideas of aerodynamics don’t apply here. Normally, air would flow around anything moving through it. But the air molecules in front of this ball don’t have time to be jostled out of the way. The ball smacks into them so hard that the atoms in the air molecules actually fuse with the atoms in the ball’s surface. Each collision releases a burst of gamma rays and scattered particles.
These gamma rays and debris expand outward in a bubble centered on the pitcher’s mound. They start to tear apart the molecules in the air, ripping the electrons from the nuclei and turning the air in the stadium into an expanding bubble of incandescent plasma. The wall of this bubble approaches the batter at about the speed of light—only slightly ahead of the ball itself.

Okay, even with ideal, completely indestructible gears, even gear two only *rotates* faster. The actual velocity of the perimeter of both gears would be the same.

What if the gears are made of light?
>>703550898
The constant fusion at the front of the ball pushes back on it, slowing it down, as if the ball were a rocket flying tail-first while firing its engines. Unfortunately, the ball is going so fast that even the tremendous force from this ongoing thermonuclear explosion barely slows it down at all. It does, however, start to eat away at the surface, blasting tiny particulate fragments of the ball in all directions. These fragments are going so fast that when they hit air molecules, they trigger two or three more rounds of fusion.
After about 70 nanoseconds the ball arrives at home plate. The batter hasn't even seen the pitcher let go of the ball, since the light carrying that information arrives at about the same time the ball does. Collisions with the air have eaten the ball away almost completely, and it is now a bullet-shaped cloud of expanding plasma (mainly carbon, oxygen, hydrogen, and nitrogen) ramming into the air and triggering more fusion as it goes. The shell of x-rays hits the batter first, and a handful of nanoseconds later the debris cloud hits.
When it reaches the batter, the center of the cloud is still moving at an appreciable fraction of the speed of light. It hits the bat first, but then the batter, plate, and catcher are all scooped up and carried backward through the backstop as they disintegrate. The shell of x-rays and superheated plasma expands outward and upward, swallowing the backstop, both teams, the stands, and the surrounding neighborhood—all in the first microsecond.
Suppose you’re watching from a hilltop outside the city. The first thing you see is a blinding light, far outshining the sun. This gradually fades over the course of a few seconds, and a growing fireball rises into a mushroom cloud. Then, with a great roar, the blast wave arrives, tearing up trees and shredding houses.
Everything within roughly a mile of the park is leveled, and a firestorm engulfs the surrounding city.

>>703550338
That's an engineering problem or, at best, applied physics. Theoretical physics asks questions from "first principle" where these secondary issues have no bearing.
For instance, when deriving the permeability of free space, one must presume the terminus of an electromagnetic field is at infinity with no interruption anywhere.

Theoretically it would gain infinate mass and probably melt due to friction long before it got close...
>>703550831
Not same guy but if the larger gear has a bigger circumference then obviously it makes a full rotation slower. Gears are linked though and moving together at the same speed.

>>703552112
Do you mean Ehrenfest paradox?
In this example, the edges of both gears are moving at the same (linear) speed. So the second gear would also be moving at the speed of light.
If you construct something where one of the gears would be moving faster, I think it would gain mass as it reaches the speed of light, preventing you from accelerating it anymore

Theoretical physicists havd some of the bluest of so-called blue sky research, yes, but just because their postulations do not immediate or apparent real-world application does not mean they're jerking off.

Also, checked.
>>703549939
Say the gears do spin at the speed of light and make of some tough material. You'll need to lubricate the gears. So give the gears lube. But the gears are spinning so fast, they just spin off the lube. Still the gears spin and reaching an incredible speed. The lube doesn't even touch the gears anymore cause the teeth just fans it away. Now the gears are getting extremely hot. It hasn't even got to light speed yet. Glowing red with no lube, the material expands by a tiny nanometer and begin grind itself into oblivion because they no longer fit into each other. The gears ultimately break. And therefore OP is faggot.

>>703552503
dude i read an article on buzzfeed where a diamond conducted 10,000 thermals in like a second
>>703549939
If the teeth at the outside of gear would move fastest. If gear 1 were moving at the speed of light, the teeth of the second gear would move at the same speed, however the gears would explode before getting close...also dimond is the hardest metal.
>>703552766

that's over 9000
>>703551775

>>703549939
the gear cleavage moving at the speed of light would mean BOTH sides are moving at a tangential speed of light
even though gear two would have faster rotation, neither would be surpassing the speed of light

Classical mechanics does not work in high speeds. Matter becomes energy and time stops. Memes transcends our cosmos.
>>703551030
Not really. It's not that difficult to calculate of the wheel spinning at relativistic velocities (the integral is ugly, but that's not a fundamental problem) and you'll see that no matter how small the smaller gear is, it's energy will be infinite when any part of the assembly reaches the speed of light (btw, rotating "at the speed of light" does not make sense -- speed of light is linear velocity, rotation is measured in angular velocity).
So you either need a power supply with infinite power if you want to accelerate the system in finite time or you need to accelerate for infinite time if you have a finite power supply. You can probably see that we reduced the problem now to childish questions of the type "what happens if unstoppable force meats unmovable object" -- i.e., nonsense that doesn't belong in the realm of physics.
>>703552766
Easy. Internal cooling with pipes inside gears. Use liquid nitrogen.

*calculate the energy
Basically what I'm trying to say is that the question doesn't make sense even if you assume ideal materials.
If brought up anything about the gears melting or how you'd need a lot of energy to power them, just kill yourself already.
>>703553481
> liquid nitrogen
Obviously they would be too cold to travel at the speed of light. Clod makes things slow down. Absolute zero is where there's no motion at all. Use lasers to heat them up instead.
fucking idiot.
>>703550401
Then the vibration would create a earthquake with enough power to most likely create a blackhole
>>703552766
What if one gear is a national socialist and is genetically, culturally, and technologically superior to other gears?
Ok. So assuming that were talking about the axis rotational speed of each gear and assuming that the teeth don't have to follow the rules of physics one can derive that if the larger gears axis speed were to reach the speed of light then the smaller gears axis speed would reach the speed of light first. In this event the smaller gears matter would convert to energy before the larger gears matter. Therefore the smaller gear wouldn't go faster than the speed of light. It would simply convert to energy before the larger gear. Correct?

your stick wouldn't be able to be pushed because of its gargantuan mass. Even if you were able to push it, it would most likely break no matter what it is made out of.

good member to get you're facts in check before posting on pornhub
>>703549939
It's entirely possible since you never specified the medium the light is traveling through (e.g. speed of light in a vacuum)... Light can be brought to a complete standstill in a bose einstein condensate.
>>703553653
The centrifugal force will push the substance back, you fucktard.
Test
>>703549939
Both of there circumferences would be running at the speed of light, so...short answer yes, the smaller gear will however make faster complete rotations, also, these are impossible conditions to make, but still don't break any rules

This.
>>703552609
Not exactly, though, with the way this question is worded, perhaps. Only tachyons can travel faster than light and, if I remember correctly, certain subatomic information via quantum entanglement. They're not breaking the laws of physics either since they are and, presumably always were, traveling faster than light. So, nothing subluminal can hit or exceed the speed of light. A better worded question would have been if gear 1 turned at 0.9c, what happens?
First, let's presume that means the tangential speed of the outter most part of the teeth as we're not given radial velocity. I would guess this;
1. Energy required for the 2nd wheel to spin as it approaches the speed of light go towards infinity therefore gear 1 never hits .9c to begin with.
However, if it can break the laws of physics and subliminal baryonic matter can travel faster than light in normal spacetime as we know it, then:
2. The spacetime continuum warps due to the funky trick of mass increasing with velocity thereunto creating more gravity which finally slows down time local time to an outside observer. This means that in non-warped spacetime the gear is still moving slower than light, or, the mass has gotten so large it created a black hole.

Without being given the radius of the gears, "tangential" is meaningless, if you're trying to calculate the velocity.
>>703549939
Even if gear one moves at the speed of light, no part of gear two would exceed the speed of light in this system.

The speed given was a linear velocity yet the question implies radial velocity. While yes, you're of course right when you say it's impossible to calculate, you're wrong in presuming it's meaningless; one can--as I did--use the word to highlight the descrepancy in the problem.

The teeth of two gears move at the same speed and the outermost edges of the gears are the fastest moving parts. Assuming a non-meaningless statement of "near the speed of light," there is no problem here - just an exorbitant amount of energy.

Even if they were made out of the strongest material in the universe, as gear 2 approached the speed of light, it would turn into pure energy when gear 1 was 40% the speed of light. Then gear 1 would follow and turn into energy as it approached the speed of light.

Introducing new question because fuck Op.
CERN is capable of moving protons to about 12 mph (~20 km/hr) shy of the speed of light. What if CERN was in space and we were able to rotate the entire particle accelerator machine? At a radius of 4 km, the accelerator would have to rotate at just 0.0133 RPM for the tangential velocity to be 20 km/h. With the accelerator running at full speed, this should get the proton to hit 1c.
So, what would happen as our "CERN in Space," pulling the proton at full speed, began rotating?
My guess is even then, regardless of what's propelling the proton (electromagnets, assemly rotation, or everything), the proton's mass would continually increasing requiring energy going off to infinity to maintain.

let's simplify this and say the wheells are circles but function the same way (moving one makes the other move too...) and that speed of light is 300000000m/s
let's say the smallet one has 1m in perimeter and rotates at 300000000rps
(speed=rps x distance --> speed of light)
then, the bigger one going 2.5x slower (i assume by the "speed ratio") would go at 120000000rps. if it is 2.5x slower then it would be 2.5x bigger, that is, have 2.5m in perimeter
120000000rps x 2.5m = speed of light
>>703559275
wrong. no partial credit. this is real life.
>>703549939
bascially, the interactions between atoms are slower than light, and if you get up to that speed, whatever particles are going zoom zoom go boom boom.

Anyone who reasonably assumes that 0.9 recurring actually equates to 1 is a retard.
>>703550831
you know what he meant, fuckwit
the gear with 20 teeth will make a full rotation faster because it's smaller and therefore less distance to rotate. For the time it takes gear 1 to rotate fully, as in have all 50 teeth at the same position, gear 2 would rotate 2.5 times. But the gear itself is not traveling any faster, again, because they are locked together as gears.
>>703559118
what if they built a larger version of the CERN accelerator and put the smaller existing one inside of it? Then there's no need to send a whole particle accelerator into space.
This is exactly the same question as if you had a flashlight traveling near the speed of light, and turned it on. If you had a long straight accelerator and built a ship around it to accelerate the whole thing to however fast, then turned on the accelerator, you'd have the same effect. it starts to get into relativity, and the speed of the particle in our view is one number, but the particle itself feels like it's traveling at a different speed. It all gets timy-wimey-wibbly-wobbely

diamond breaks more easily than most metals. It doesn't bend so it shatters easily
The size of the smaller gear will literally change. The space between each tooth of the gear will shrink so that it doesn't go past the speed of light. I'm not even joking. Physics is weird when you get near the speed of light. If you don't believe me, try it. Tie up a gear to the beam of a laser pointer and fire that shit up.
You'll learn all this stuff in first year physics. If you're interested in more, look up "special relativity".

10x - x = 8.999... not 9
there's your mistake dipshit
>>703559921
0.999 = 1
Computational science would agree. Somewhere a calculation occured where the the irrational numbers were rounded or cut off where its negated value was smaller than machine epsilon yet still needed to get the "correct" answer of one. This is a limit of how computational devices ha dle irrational numbers. If the number is that close to one, yes, it's read as 1.
0.999... != 1
Pure mathematics would agree. If 0.999... does indeed equal 1, please tell me where on the graph y = x/(x+1), does y equal 1? It doesn't, ever. 1 is the asymptote.
lim x-> inf of x/(x+1) = 1. Its limit, its asymptote, is 1, but the equation and 0.999... in of itself never equals 1.

>>703550951
Due to extensive research done by the University of Pittsburgh, diamond has been confirmed as the hardest metal known to man. The research is as follows. Pocket-protected scientists built a wall of iron and crashed a diamond car into it at 400 miles per hour, and the car was unharmed. They then built a wall out of diamond and crashed a car made of iron moving at 400 miles an hour into the wall, and the wall came out fine. They then crashed a diamond car made of 400 miles per hour into a wall, and there were no survivors. They crashed 400 miles per hour into a diamond traveling at iron car. Western New York was powerless for hours. They rammed a wall of metal into a 400 mile per hour made of diamond, and the resulting explosion shifted the earth's orbit 400 million miles away from the sun, saving the earth from a meteor the size of a small Washington suburb that was hurtling towards mid-western Prussia at 400 billion miles per hour. They shot a diamond made of iron at a car moving at 400 walls per hour, and as a result caused several wayward airplanes to lose track of their bearings, and make a fatal crash with several buildings in downtown Chicago. They spun 400 miles at diamond into iron per wall. The results were inconclusive. Finally, they placed 400 diamonds per hour in front of a car made of wall traveling at miles per iron, and the result proved without a doubt that diamonds were the hardest metal of all time, if not just the hardest metal known to man.

If gear 1 turned at the speed of light, gear 2 would turn at the speed of light. (Assuming either of them could do so without ceasing to exist.) The linear velocities of the gears' teeth have to be equal because of the way they lock together. Otherwise the teeth would be fazing through each other.
The ANGULAR velocities are going to be different, but fortunately there's no known universal angular speed limit. Just a linear one.
>>703565818
nailed it

The linear speed of both is the same.
>>703553327

>>703549939
Physicist here. Let's say these were magic gears that could be turned super fast without being torn apart, you wouldn't ever be able to rotate the smaller gear to faster than 40% the speed of light. It would take exponentially more and more energy as the larger gear's apparent inertia would increase further and further.
>>703565818
other people already beat you to it, so you could have saved your time, but this is a b8 thread so everyone could have saved their time
BTW
right around the event horizon of a black hole there is a layer of light that is stuck in a perfect revolution around the black hole, and since many blackholes are of different diameter even horizon (think supermassive vs reg) so since there is that layer on all blackholes (theoretically, can't actually measure) maximum angular speed is limited by light speed as tangential speed
This thread grinds my gears.

your post proves you dont understand much
>>703565818
But you have to assume that they're made out of jello. Therefor linear velocities may not equal to eachother.
Nice try...
>>703566699
That makes sense, I was thinking about that as I wrote that line. "Wait, is that right? There must be an angular speed limit." But I gotta ask, if that's the case, wouldn't the maximum possible angular speed change depending on the radius of the thing rotating?
I guess the absolute maximum angular speed would be the speed of a photon orbiting a point at a radius of one Planck length or something. (Assuming it's possible for any sufficient mass to be concentrated in an infinitesimal space such as that.)

But then it would be orbiting around a point that doesn't exist???
... Hmm, maybe that's not a problem. As long as the position of the photon itself is always well defined, what does it matter where it's orbiting around?
Makes sense. I like you too.
theoretical physics is useless. What has it scienced so far?
>>703567867
Thank you for the clarification. It was starting to bug me.
>>703568166
If r = 0 then necessarily v = 0 and omega is indeterminate because it's of the form 0/0
>>703568261
you can assume that the gears are massless. made of dense air.
>>703567997
>>703567578
btw, theoretically it would be possible to get a photon to spin around a planck length
theoretically since beyond the event horizon distance is meaningless and equivalent to a singularity at planck length, any photon ring around a black hole is spinning around a planck length (assuming the photon ring is around the event horizon exactly)
>>703551434
lmao fukkn trolld newfag XD
Okay, time to learn about gears.
Something can't rotate 'at the speed of light' because speed is a measure of distance over time. What you meant to say was 'what if the outer edges of gear 1's teeth moved at the speed of light?', and in that case, fucking nothing interesting happens. The outside edges of gear 2 turn at the same speed. No law is broken.
>>703549939
something cannot "spin" or "turn" at the speed of light. however the outermost point of a circular object in rotation can, in theory, have an instantaneous velocity vector up to the speed of light. which would mean that any connected object (the other gear) would have an outermost point with an equal instantaneous velocity. so basically, while the gear RPMs would be different, the velocity of the gears remains equal.
