Well one day someone is gonna solve it and he is sure to get a nobel prize.

>>8736181
Oh, scientists do understand it. Its just that you're too much of a brainlet to understand the explanation and would rather prefer invisible leprechauns holding the bicycle upright as an answer.

Not falling for that one again.

>>8736181
The internal gyroscope theory.
The centre of gravity of the bike is very low unless you stand up on it.
This means that so long as it maintains velocity sufficient enough to overcome base principle acceleration it can remain standing upright. :D

Invisible eye tentacles hold it straight

Prove me wrong

>>8736213
Pshh
you are like a little baby watch THIS
As you proceed to push down on the peddle the bike moans softly and begins twisting its chain. Slowy you flick on its nub and it rings out in a soft ring. This causes it to get so wet that it lubricates off the floor and gravity ceases to affect it. When you begin moving the peddle more and more it begins to call you Senpai, the less you notice it the more it will move. This is the REAL reason bikes work.

>how bicycles stay upright

they don't stay upright, that is an illusion, they are constantly in the process of falling to one side or another, and you are balancing using your body weight to try to find the center line.

>>8736181
Mumei a shit

>>8736256
Y-YUO A SHIT!

gyroscopes are insufficient to explain bicycles. You can cancel out the gyroscope effect and still ride a bicycle. It's dumb from first principles too, there's not nearly enough mass in bicycle wheels to generate enough torque to keep a bike upright.

Constant balance corrections by the rider are critical, aided by the angle of the front forks.

Net force is zero

Here's my attempt

A bicycle rider falling on their side would mean that the center of mass would have to travel at a larger distance than just going straight and that falling over would actually require more energy.

they don't unless a cyclist is on it to use his muscles and balance it.

>>8736978
also, some of the force acting perpendicular to the bike would get "absorbed" by the spinning wheels

Jesus fuck, you guys, this is PHYS 101 stuff. No diff eq. or gyroscopes needed. As something rotates, it has more rotational velocity. This makes it harder to rotate it in an opposing, perpendicular direction i.e. torque, making it more stable the faster you go. Why are brainlets making it so unnecessarily complicated?

>>8736989
Thank god, someone understands

>>8737027
that's literally gyroscopes you pinass

>>8737030
No, gyroscopes can assume any axis of rotation for balance, and often break often and easily, as they can be used for balance. Same concept, not the same thing. Sorta like a flywheel on an engine. Unless you can point to a gyroscope on a bike, I disagree.

Too bad bicycles with zero spin angular momentum still balance.

>>8737055
You have a point. I thought we were talking about in motion, but I don't mind admitting I'm wrong.

>>8737065
We are talking about in motion.

>>8737034
gyroscopes require two points of motion to function right?
Well the first point of motion is the bike.
The second is hidden inside the earth itself where the center of gravity is.
Underground.

>>8736987
how many attempts did they make until they got the desired result?

>>8737208
I assume not many, it's pretty easy.
If you have a bike go try it.

>>8737208
One, because it's basically impossible to not do.

As long as the bike has sufficient velocity, it will stay upright on a flat surface. When the bike starts to tilt to the side, the front wheel will turn to that side, ensuring the center of mass stays in the center (in terms of left and right) of the bike.

Scientists btfo.

>experimental physicist

centripetal force + autostabilizing due to one fixed wheel

i highly doubt a bike with two turnable wheels would stay straight for long

>>8740180
>autostabilizing due to one fixed wheel
That's not every descriptive.

>>8736181
It's autostabilization

the front wheel is canted for a reason, as any tilt in that direction will naturally cause the wheel to go in that direction, stabilizing the bicycle. gyroscopic effect does not play nearly as large a role as that.

just because you can't understand bicycles doesn't mean others can't.

>>8738143

the rest of the people would tell him how to fix it if the cables were massless and the elevator had a uniform mass distribution

The answer has almost nothing to do with gyroscopes, and even without gyroscopes it's fairly simple high school stuff - if you paid any attention during the most elementary physics courses in motion available you would know the answer.

As the bicycle tilts to any one side, it wants to steer in that direction, because the wheels are circular. Anything going in circular motion has some centripetal force that keeps it in that circular motion - in this case, friction on the back and front tires. Friction points towards the center of the circle, and because the center of the mass of the bicycle is above the bike, the resultant torque acts to straighten out the thing.

You can mess around with varying the parameters and you'll notice that tighter circles mean greater force, so that leaning more will actually force you to straighten more, and leaning less will cause you to straighten less - the torque is a restoring force. Similarly, increasing velocity increases force by a factor of velocity squared, so going just a bit faster increases the correctional force by a factor of 2, which explains why it's so difficult to stay upright at a crawling speed and much easier once you get up to speed.

As long as the correctional torque is greater than the torque of gravity, then the bike will stay upright. You should note that this does not mean drive a heavier bike - torque provided by gravity also depends linearly on m, and will act just as well against you as for you in terms of stability.

>>8740331
Wrong you can build a bike without that cant and it will stabilize.

Infinite regret because the only thing in philosophy that can have a shot at certainty of mathematical truths is analytic philosophy, and if you wanna do that just do math instead.

>>8736232
If it were only this mechanism only it would be just as easy to balance standing still as it would riding.
