(c) An internally pressurised cylinder has a factor of safety, FoS, with regards to yielding of FoS = 3 according to the Maximum Principal Stress Theory and FoS = 2 according to the Maximum Shear Stress Theory. Calculate the radial stress, ,, in terms of the tangential stress, o, at the inner surface of the cylinder. (4 marks) 4 (d) A thin square plate of width, w = 100 mm, is made from steel with a yield strength of, o=800 MPa, and contains a hole of radius, r= 10 mm, at its centre. If the plate is subjected to a tensile stress, o=275 MPa, parallel to the plate edge then what will be the maximum residual stress at the edge of the hole upon unloading? (3 marks)
