The cylindrical pressure vessel shown in the figure has an inside diameter of 995 mm and a wall thickness of 12 mm. The cylinder is made of an aluminum alloy that has an elastic modulus of E = 72 GPa and a shear modulus of G = 27.3 GPa. Two strain gages are mounted on the exterior surface of the cylinder at right angles to each other. The angle O is 24°. If the pressure in the vessel is 1.81 MPa, determine: (a) the strains that act in the x and y directions. (b) the strains expected in gages a and b. (c) the normal stresses o, ando,. (d) the shear stress Tnt. 90°
