Inertia Wheel

Return to Rotational Dynamics

Description:

This is an aluminum disk with two diameters which is free to rotate. The moment on inertia remains constant but it is possible to exert two different torques with a single mass. Set this at the edge of a table, roll a string or tape (more visible) around one of the diameters and attach a mass. The rate of fall is significantly different for the two diameters.
