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

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.
