Concept explainers

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

a) Compute the torsional shear stress in a circular shaft with a diameter of 50 mm that is subjected to a torque of 800 N.m.

b)If the shaft of Problem above is 850 mm long and is made of steel, compute the angle of twist of one end in relation to the other.
