A 30-in. length of aluminum pipe of cross-sectional area 1.85 in2 is welded to a fixed support A and to a rigid cap B. The steel rod EF, of 0.75-in. diameter, is welded to cap B. Knowing that the modulus of elasticity is 29 X 106 psi for the steel and 10.6 X 106 psi for the aluminum, determine (a) the total strain energy of the system when P = 8 kips, (b) the corresponding strain-energy density of the pipe CD and in the rod EF.
