SD3 - Torsional Vibration Apparatus

This benchtop mounted unit is used to study torsion and torsional vibration. Also supplied with the apparatus is a annual torsion arrangement, which allows a known angular twist to be applied to the specimen.
A cord is wrapped around one of the large discs and a load is applied via a hanger and weights set. The angle of twist for incremental loading is recorded and the modulus of rigidity can be calculated. Oscillations sensors are mounted integrally with each mass.
