Moment of inertia and angular acceleration with a precision pivot bearing

Principle

A moment acts on a body which can be rotated about a bearing without friction. The moment of inertia is determined from the angular acceleration.

Benefits

• Long runtime
• Nearly friction-less movement due to precision bearing and precision pulley
• Steady set-up prevents interferences

Tasks

From the angular acceleration, the moment of inertia is determined as a function of the mass and the distance from the axis of rotation

1. of a disc
2. of a bar
3. of a mass point
