Bicycle Wheel Gyroscope On Rope
To illustrate gyroscopic precession in a surprising way. ◙
Bicycle wheel gyroscope and wheel.
Set up the students for this by showing them this same bicycle wheel gyroscope on a rigid pivot. Then ask◙them if one of the conditions to obtain precession might be a strong, rigid pivot!
Spin the wheel, then hang it from the end of the rope with the rope vertical and the wheel axel in a horizontal orientation. It will precess with the rope remaining vertical. ◙
