A thin-walled cylinder of average radius 50 mm, and wall thickness 1.0 mm is of length 500 mm, and is built into a wall at one end. A distributed load of 50 N/mm is applied over 100 mm from the free end, and the cylinder contains an internal pressure of 5.0 MPa.
Calculate the principal stresses, and the maximum shear stress. (0 MPa, 410 MPa, 250 MPa)
