Description

The resistance with which a rigid body opposes a change to its rotation is indicated by the
mass moment of inertia. Here, the behavior of the body depends on its mass and the
distribution of this mass relative to the axis of rotation. Mathematically, the quotient of the
rotary moment and the angular acceleration is the mass moment of inertia.
A support rod supports the rotary axis with the studied body. The rotary axis is accelerated
by a weight, pulley and cable with a drum. This results in a uniformly accelerated rotational
motion. Using the measured time, mass and acceleration distance, we can calculate the
mass moment of inertia. Systems with different masses and mass distributions can be
studied in various geometries.
Using a rotating bar with masses, it is possible to study the mass moment of inertia as a
function of the radius.
