Torsion Testing Machine is a mechanical testing instrument capable of evaluating the twisting or torsional properties of various materials such as metals, polymers, and composites. This machine applies torque or rotational force to a specimen to measure its yield strength, modulus of elasticity, shear modulus, and other mechanical properties. Moreover, Torsion Testing Machine comprises of a motor, gear system, torque sensor, and a load cell that applies torque and measures the twisting force. The machine is available in various configurations depending on load range, specimen size, and angular displacement.
