Prob. 3.4-6. A magnesium-alloy rod (E = 6.5 x 10 ksi) of diameter d 1 in. is encased by a brass tube (E, = 15 x 10' ksi) with outer diameter d 1.5 in.: both have length L = 20 in. An axial load P = 10 kips is applied to the resulting bimetallic rod. (a) Determine the normal stresses and , in each material, assuming that the magnesium rod and brass tube are securely bonded to each other. (b) Determine the elongation of the bimetallic rod. H
