Rotational Moment of Inertia Apparatus Experiments

This apparatus is designed to measure the rotational inertia of objects using the trifilar pendulum method. It enables the study of pendulum motion, verification of the parallel axis theorem, and determination of the center of mass and rotational inertia of both regular and irregular objects when used with additional accessories.
