Description

This simple piece of apparatus has been designed for student laboratory exercises to investigate the elastic torsion characteristics of circular bars.

The range of experiments include:

1. The verification of the elastic torsion equation
2.  The determination of the Modulus of Rigidity for different materials

Torque is applied to the specimen bars by means of a spring balance and torque arm and a dial gauge in contact with the arm enables the angle of twist to be measured. A range of specimens in different materials is supplied as standard.
