HSM2 Torsion of Bars

HSM2 Torsion of Bars

Apparatus to understand and investigate directly the relationship between the torsional load applied to a round bar and the angular twist produced and how this relationship varies with the beam material and it’s cross sectional polar moment of area. Specimens are rigidly held in a clamp fixed to one end of the bench top base frame of the apparatus. A bearing at the other end contains a short shaft with an integral pulley and chuck.

The pulley has cord wrapped around its periphery to allow torque to be applied using the load hanger and calibrated weights supplied. A rotation scale and pointer can be attached to any point on the specimen's length to find the angle of twist of the specimen. A specimen set is supplied with a variety of specimens in round bar and differing materials.
