The design used in the Model 210 torsion testing machine is basically the same as the universal test machine except that a "clockwise/counterclockwise" motion is used instead of linear compression and tension.
Depending on the model, machines include a computer with control software for the visualization and storage of the data, or a digital readout for simple tests.
The units of measure are modified for this application - reporting Nm and degrees of angle. The software reports all characteristics of torsion testing.
