Moment of inertia and angular acceleration with Cobra SMARTsense and a precision pivot bearing
Principle
If a constant torque is applied to a body that rotates without friction around a fixed axis, the changing angle of rotation increases proportionally to the square of the time and the angular velocity proportional to the time.
Benefits
- Long runtime
- Nearly friction-less movement due to precision bearing
- Steady set-up prevents interferences
- Data logging reveals instantaneous results during measurement
