This is an educational machine for an extensive range of torsion tests.

The machine consists of a torque applying unit, and a torque measuring unit sliding on two parallel stainless steel tubes. The torque applying unit is a two stage reduction gear with a motor, and angular displacement measuring instruments. The torque measuring unit has a torque arm with a two direction load cell. The specimen is held at each end by hexagonal drive sockets which fit on the input shaft from the gear box and the torsion shaft. The motor is automatically stopped when the specimen is broken. The torsion shaft column can be slided on two parallel shafts to accommodate specimen length. The equipment is a table top type with adjustable footings.
