Torsion | Torsional Deformations of a Circular Bar | Mechanics of Materials | Mech Engg. Shear Strains at the Outer Surface Shear Strains within the bar Circular Tubes Torsion refers to the twisting of a straight bar when it is loaded by moments (or torques) that tend to produce rotation about the longitudinal axis of the bar. Moments that produce twisting of a bar, such as the moments T1 and T2, are called torques or twisting moments. Cylindrical members that are subjected to torques and transmit power through rotation are called shafts
