The hypothesis used in developing the stress and strain in the shaft is that all points on a cross-section of the shaft experience the same angle of twist. The angle of twist for a section of length L ...

In these experiments, rods and tubes of different materials will be subjected to a torque and their torsional deflection measured using an optical lever technique. Torsional stress-strain curves will ...

Little is known on the rotational torque that players experience on these fields. High rotational torques between the shoe outsole and the sports surface has been correlated with torsional injuries of ...
