Experiment 1: To find the moment of inertia of a fly-wheel about its axis of rotation
Apparatus: A fly-wheel, different masses, a mass provided with a hook, a strong and thin string (thread), stop watch, a meter scale, a vernier calliper and chalk
Theory: A flywheel is a simple heavy wheel with a long axle supported, in bearings, and it can rest at any position. It is possible as the center of gravity (CG) lies on the axis of rotation of the wheel.
Figure 1: Flywheel apparatus
For calculation of the moment of inertia of flywheel, a mass m is attached to the axle of the wheel by a cord wrapped several times round the ...
