Rotational Moment of Inertia Apparatus

Descriptions:

• This apparatus uses the three-string pendulum method to determine the moment of inertia of a rigid body.
• A photoelectric sensor combined with a time counting device is used to measure the torsional oscillation period of a hanging plate.
• Through the experiments, students can understand the physical principle of the moment of inertia and learn the measurement method with factors related to the amount of moment of inertia.
• Moment of inertia is a physical quantity for the representation of the inertial amount of a rotational object.
• It is dependent on the mass distribution and the shaft position of the rigid body.
