This Fly Wheel (20 cm Diameter) is a sturdy and accurately balanced physics laboratory apparatus used for experiments on rotational motion and moment of inertia. It is designed to help students observe how a rotating body stores energy and how its motion changes under applied torque.

This apparatus features a finely machined cast iron wheel of approximately 20 cm diameter with a 4.4 cm wide rim, mounted on a horizontal shaft supported by low-friction ball bearings for smooth rotation. A reference mark on the wheel, along with a fixed pointer, helps in accurate counting of revolutions during the experiment.

The shaft is provided with a diametric hole for attaching the supplied cord and pin arrangement. The base includes mounting holes for secure wall installation, making the apparatus stable and suitable for repeated laboratory use. Supplied complete with cord and hook.
