Simple Flywheel Apparatus

A mark on the Simple Flywheel Apparatus and a pointer on the bracket enables the revolutions to be counted and timed with the stop watch supplied. From the timings of a known number of revolutions, students can then verify the expeirmental capabilities of the apparatus. A steel disc Ø250mm diameter and 30mm thick is mounted on a shaft running in precision bearings housed in a substantial wall bracket. A cord, load hanger and set of weights are provided to start the flywheel rotating.

Experimental Capabilities:
To compare experimental and calculated moments of inertia of a disc
To study the energy transformations and to demonstrate that a flywheel can be used to store energy
To verify the second law of motion applied to a flywheel, ie the relationship between torque and angular acceleration
