The torsion test primarily measures, at a certain moment or load, how much the bar or specimen is twisting and at what angle this test can also be done in reverse order measuring the angle first, and recording the torque on the test material the testing of a “torque-angle” graph can be somewhat similar to a “stress-strain” curve.
