Rolling disk on inclined plane (TM 611)

Inertia in rotational motion on an inclined plane and in a physical pendulum

CodeTM611

Description:

  • The mass moment of inertia is a proportionality constant, which depends on both the body and the position of the body’s rotation axis.
  • By measuring the rotary moment and the resulting angular acceleration, we can experimentally determine the mass moment of inertia.
  • To do this, the TM 611unit offers rolling experiments on an inclined plane and pendulum experiments with a physical pendulum to determine mass moments of inertia experimentally.
  • In the rolling experiment, the inclination of the inclined plane is set through height adjustment and read on a goniometer.
  • A disk rolls down the track.
  • The time and the acceleration distance are measured, and the mass moment of inertia is calculated.
  • To conduct the pendulum experiments, the disk is hung in a mount.
  • The rotation axis of the disk is displaced by a specific distance from the centre of gravity.
  • The disk is deflected and rolls back and forth in a pendulum motion.
  • The mass moment of inertia is calculated from the measured time during the swaying, the mass and the distance to the centre of gravity (Steiner’s theorem).
  • Two different disks are available.
  • The experiments are precisely aligned with spirit levels.
