How Does Precession Keep a Spinning Bicycle Wheel Upright?

Click For Summary
A rotating bicycle wheel remains upright due to the principles of angular momentum and precession. When held at one side of the axle, the forces acting on the wheel create a tendency for the top to move left and the bottom to move right. However, as the wheel spins, these forces counteract each other because the wheel's rotation continuously changes the position of the forces. This dynamic balance prevents the wheel from falling over. Understanding these concepts is crucial for grasping the mechanics of gyroscopic stability.

I am trying to understand how a rotating bicycle wheel doesn't fall over when you hold it on one side of the axle . I read a thing and it says , the top of the wheel wants to go to the left and the bottom of the wheel want to go right but when the wheel rotates these forces appose because that part of the wheel is now in a new place ,
is this correct , any input will be much appreciated .

That is exactly right.
 
Thanks for he answers and the videos .
 
I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
