一般說明

To perform the tests a metallic rod is fastened by clamps and subjected to the testing force. Force is gradually applied on the rod to observe the elastic tension generated.

The force moment or torque is applied by a dynamometer with a lever. Deformation generated by the torsional stress is obtained by reading a dial gauge in contact with the arm. The torsional deformation angle is obtained by a simple trigonometric identity, providing the unit with important didactic characteristics.

Steel, brass and aluminum rods are supplied to perform the practical exercises. Additionally, rods made of other materials can be employed.
