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

2. The maximum torsional moment a solid shaft can bear is T = 0.2r kN . m. If the allowable
shear stress of the material is [t] = 50 MPa, design the diameter of the shaft based on the strength
condition
