A flywheel is a rotating mechanical device that is used to store rotational energy. The amount of energy stored in a flywheel is proportional to the square of its rotational speed.
This apparatus helps students to get a basic understanding of the mechanism of a flywheel and for calculations of the moment of inertia of the flywheel.
It is about 20 cm in diameter and 45 mm wide, turned and carefully balanced, mounted on a horizontal shaft, held in ball bearings.
There is a small peg on the axle. One end of a cord is loosely looped around the peg and its other end carries the weight-hanger.
The wheel is marked and the pointer is fixed to the bracket.
The bracket has four holes and can be fixed to the wall.
Set of slotted weights and weight hanger can be bought separately.
