This apparatus is designed to demonstrate the working principle of flywheel and its practical significance in industry. Flywheel is used to store rotational energy when the supply of energy is more than the required, and delivers when requirement of energy is more than the supplied.
This apparatus consists of flywheel mounted on a shaft and whole structure is attached to the base plate. Cord is wounded on the axle carrying dead weights and hanger. Students can calculate the inertia of flywheel by adding weights on hanger.
