Objective: Determine the moment of inertia of a horizontal rod with additional weights attached
The moment of inertia of a body about its axis of rotation depends on the distribution of its weight in relation to the axis. This is to be investigated for the case of a horizontal rod to which two additional weights are attached symmetrically about the axis of rotation. The rod is coupled to a torsion spring, and its period of oscillation increases as its moment of inertia, which is determined by the additional weights and their distance from the axis, is raised.
