ME2.2 Bicycle Wheel as Gyroscope
A motor allows the tire to spin at a high speed. Suspend both sides of tire from the ceiling by ropes. Once the tire is spinning, detach the motor and one supporting rope. The tire will then act as a gyroscope keeping the axis of rotation in a level plane.
Torque controls the precession of the gyroscope. This torque is produced by hanging weights on the gyroscope
ME2.4 Inclined Plane
This shows that the moment of inertia is dependent of the size and weight of an object and dependent only on its geometry. Objects with different masses but the same geometry will roll at the same rate, except for a small factor due to friction.
