A magnesium-alloy Prob. 3.4-6. diameter d rod (E = 6.5 x 10 ksi) of 15 x 1 in. is encased by a brass tube (Es 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.
