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.

Question

Q3 The steel shaft, shown in the figure, is made from two segments: AC has a diameter of
30 mm and CB has a diameter of 55 mm. If it is fixed at its ends A and B, determine the
magnitude of the applied torque T if the reaction at A is 75 N.m. Use G= 75 GPa.
