Apparatus of Shear Modulus and Rotational Moment of Inertia for Mechanics Physics Lab

This Apparatus of Shear Modulus and Rotational Moment of Inertia for Mechanics Physics Lab is designed for studying the mechanical properties of materials and the principles of rotational dynamics. The apparatus enables accurate measurement of shear modulus and determination of the rotational moment of inertia using the torsional pendulum method. A specially designed hanging claw replaces conventional disk plates, allowing different rigid bodies to be mounted in either horizontal or vertical orientations for comprehensive rotational studies. The integrated Hall sensor and electronic timing system provide precise and repeatable measurements of torsional oscillation periods.
