To determine the value of modulus of rigidity of the material of a given the help of torsional pendulum
The Torsional Pendulum Apparatus is a physics laboratory instrument designed to determine the modulus of rigidity (shear modulus) of the material of a given wire using the torsional pendulum method. The apparatus consists of a rigid body or circular disc suspended by a thin wire. When the suspended body is twisted through a small angle and released, it performs angular oscillations due to the restoring torque produced by the twisted wire.
By measuring the time period of torsional oscillations and determining the relevant dimensions and physical parameters of the wire and suspended body, students can calculate the modulus of rigidity of the wire material. The experiment demonstrates the relationship between torsional stiffness, restoring torque, moment of inertia, and oscillation period.
Ideal for physics laboratories in schools, colleges, universities, and engineering institutions, the Torsional Pendulum Apparatus provides practical learning in torsion, rotational motion, elastic properties of materials, and experimental mechanics.
Aim / Objective: Determine the stated elastic property of a material using the method specified in the experiment title.
