(a) A cylindrical pressure vessel with hemi-spherical ends has a radius of 0.25 m, and a wall thickness of 3 mm. The material from which it is made has a yield stress of 200 MPa. Sketch a diagram showing the stresses induced in the vessel. Determine the maximum internal pressure which may be sustained if yielding is to be avoided.
