Kinetic model: flywheel (TM 612)

investigation of uniformly accelerated rotational motion

CodeTM612

Description:

  • The resistance with which a rigid body opposes a change to its rotation is indicated by the mass moment of inertia.
  • It is a measure of the inertia of a body in rotation.
  • Using the TM 612kinetic model, we can conduct basic experiments on uniformly accelerated rotational motion.
  • The experimental unit comprises a flywheel with shaft, a cable and a set of weights.
  • The shaft forms the axis of rotation in the centre of gravity of the flywheel.
  • It is mounted on two bearings.
  • One end of the cable is attached to the shaft.
  • A weight is attached to the other end.
  • The attached weight sets the flywheel in a uniformly accelerated motion.
  • The time needed to roll down is measured and compared to the times for other weights.
  • The mass moment of inertia of the flywheel is calculated from the measured time, the mass of the flywheel and the acceleration distance.
  • The experimental unit is designed to be fixed to a wall.
