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 reduction gear with a hand wheel, 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. Different sizes of drive sockets are provided. The torsion shaft column can be slided on two parallel guides to accommodate specimen length. The equipment is a table top type with adjustable footings.

Instruction manual is also included.
