Rotational Inertia Experiment
The Rotary Motion Sensor provides a sturdy, low-friction rotational platform for the Ring and Disk, in addition to measuring the resulting angular acceleration. A known torque is applied to the ring and disk by the weight hanging over the pulley. The rotational inertia of the ring and disk are determined from the resulting angular acceleration. The procedure is repeated for the disk alone.
Rotational Inertia Experiment
The rotational inertia of the ring and disk is calculated from the angular acceleration obtained from the slope of this Angular Velocity vs. Time graph.
