A cylindrical pressure vessel hold gas at an internal pressure of P = 0.6 MPa, the inner radius of the tank is r = 0.6 m, and the uniform wall thickness t = 2 mm. The wall of the vessel is made of a material with a yield stress of Sy = 350 MPa. 02. 01 -02 01 (a) Calculate the hoop stress. (b) Calculate the longitudinal stress. (c) Calculate the magnitude of both principal stresses. (d) Calculate the direction and magnitude of the maximum in-plane shear stress. (e) Draw the corresponding Mohr's circle. (f) Sketch the principal and maximum shear stress elements and show their orientation with respect to the x axis. (g) Calculate the maximum shear stress.
