Torsion - Lab Report Example ners, are frequently subject to this perspective of torsion testing mainly for the sake of determining their levels of strength especially under duress (AMERICAN SOCIETY FOR TESTING MATERIALS, 1961).   Torsion test may take place under three major categories. These includes; failure testing, operational testing, as well as proof testing. Failure testing has to do with the aspect of material twisting till it breaks (HELLER, 1975).  Proof testing on the other hand plays a role of observing whether specific material can withstand a certain torque load quantity over a given timeframe. Finally, operational testing is meant for testing particular products for confirmation of their elastic limits before taking them to the market. It is often deemed very critical to take records of each and every torsion test result. This is done through creation of a stress-strain graph with both X-axis and Y-axis bearing the values regarding the angle of twist and the torque respectively. With use of a torsion testing device, twisting is done at quarter-degree level of increments with subsequent recording of the torque it can actually withstand. The twist angle corresponds to the strain, and the measured torque corresponds to the stress. A torsion test is often conducted on various materials so as to determine their torsional features. These properties includes; Ductility, shear elasticity, ultimate and yield shear strengths, as well as the rapture modulus. Torsion test performance is mainly done for various distinct purposes and significance (KEETON, 1975).  This is because, by testing products such as switches, biomedical catheter tubing, automotive steering columns, fasteners, among others; manufacturers gets the ability of simulating service conditions, checking of product quality, designs verification, and the aspect of ensuring adequate manufacturing techniques. The material’s elastic limit refers to the point upon which it will no longer return back to its unique size or
