The cylindrical portion of a compressed-air tank is fabricated of steel plate that is welded along a helix that makes an angle of 70 with respect to the longitudinal axis of the tank. The inside diameter of the cylinder is 48 in., the wall thickness is 0.5 in., and the internal pressure is 240 psi. Determine the following quantities for the cylindrical portion of the tank: (a) the axial stress a and the hoop stress h, (b) the normal stress and shear stress on planes parallel and perpendicular to the weld, (c) the maximum inplane shear stress, and (d) the absolute maximum shear
