A torque of magnitude T = 12 kNm is applied to the end of a tank containing compressed air
under a pressure of 8 MPa (Figure Q1). The tank has a 180 mm inner diameter and a 12 mm
wall thickness. As a result of several tensile tests, it has been found that tensile yeild strength
is σy = 250 MPa for thr grade of steel used. Determine the factor of safety with respect to yeild,
using:
(a) The maximum shearing stress theory
(b) The maximum distortion energy theory
