a) Assuming circumferential stress σ and longitudinal stress 2 remains constant through the thickness of the pressurized vessel, label all the stress components that are present in the 3D stress element A, with the shaded portion lying on the outermost surface of the cylinder. Find the maximum shear stress for this 3D stress element considering Pint = 2 MPa, R = 100 mm, t = 10 mm. Outermost Surface of a Pressurized Cylinder
