Moment of Inertia Apparatus PMK 380 is designed to determine the moment of inertia of many kind of object with oscillation method. Oscillation occurs caused by torque which is applied to the spiral spring which is mounted on the axis of this device. By measuring the oscillation interval and using a calculation, the moment of inertia of an observed object can be determined. Spring constant should be determined first prior to the experiment.

Oscillation interval measurement can be done manually by using stopwatch or, for better accuracy, can be used Timer Counter AT-01 and Photo Gates which can record up to 20 measurement data.

Provided with experiment manual book.

Experiment topics:

• Spiral Spring Constant of Moment of Inertia Apparatus
• Moment of Inertia of Body
• Steiner’s Theorem
• Moment of Inertia of Bar
• Inertial mass of Dumbbel

Some experiments need some other supporting tools or other components that can be borrowed from other kit.
