Test: Torsion of Shafts - 2 - Mechanical Engineering MCQ

If a shaft is rotating at N revolutions per minute with an applied torque TN-m, the power being transmitted by the shaft in watt is

For a circular shaft of diameter d subjected to torque T, the maximum value of the shear stress is

What is the maximum torque transmitted by a hollow shaft of external radius R and internal radius r?

A solid shaft of circular cross-section is subjected to a torque T which produces a maximum shear stress τ_s in the shaft. The diameter of the shaft should be

The ratio of torque carrying capacity of solid shaft to that of a hollow shaft is given by
