The application theory of torsion test machine in production teaching

The torsion test machine loads the torque of the test sample through a loading system, and calculates and displays the test data through a data acquisition and processing system, display system, etc. It is mainly used to test the torsional resistance of materials, such as measuring the torque of carbon steel, shear modulus G, torsional yield point τs, torsional strength τb, torsional angle, torsional yield strength, non-proportional torsional strength, etc., and can draw the torque-torsional angle curve, torque-angle curve, torque-time, torsional angle-time and other curves.
