A strain gage is mounted at an angle of 30° with respect to the longitudinal axis of the cylindrical pressure. The pressure vessel is fabricated from aluminum [E = 10,000 ksi; ν = 0.33], and it has an inside diameter of 54 in. and a wall thickness of 1.00 in. If the internal pressure in the cylinder is 798 psi, determine the maximum shear strain on the outer surface of the cylinder.
