Torsion 2 GATE 2024 Fundamental Quiz

A Hollow circular shaft of outer diameter 120 mm and inner diameter 80 mm is subjected to pure torsion. If total length of shaft is 1 m, then find the shear angle (in degrees) at outer surface of shaft. Angle of twist at free end is 5°.

Two shafts A & B are made of same material subjected to same twisting moment T. The diameter of shaft A is twice that of shaft B . The ratio of maximum angle of shaft A to that of shaft B is

A hollow shaft (outer diameter = 100 mm, & inner diameter = 40 mm) transmits a torque T, the maximum shear stress is 120 MPa.
