Problem1: The entire composite shaft shown in the following figure is manufactured using steel with a modulus of rigidity of 80 GPa. The dimensions of the composite shaft are included in the figure. Unknown torques of equal magnitude T are applied to the two ends A and D. a. If the steel material has the maximum allowable shear stress of 75 MPa, determine the maximum allowable torque T that can be applied to the shaft. b. Once you have found the maximum allowable T in part a, use that value to determine the angle of twist of end A relative to the end D.

Torsion

In mechanical engineering, torque, torsion, and twisting moment are three of the most important concepts which have different meanings. Torque is the consequence of a moment of a force that produces an angular acceleration in a body or induces rotational kinetic energy in a body. For instance, in an automobile, the power transmission shaft is a body that is always under rotation due to the external torque acting on it, this torque is created by the engine.
