Rotational Moment of Inertia Apparatus for Mechanics Physics Lab

This Rotational Moment of Inertia Apparatus for Mechanics Physics Lab is designed for studying rotational dynamics and determining the moment of inertia of rigid bodies using the three-string pendulum method. The apparatus employs a photoelectric sensing system and a precision electronic timer to accurately measure oscillation periods, enabling reliable calculation of rotational moment of inertia. Through practical experimentation, students can investigate the influence of mass distribution and axis position on rotational motion while gaining a deeper understanding of rotational mechanics.
