Prob. 3.4-6. A magnesium-alloy rod (E = 6.5 x 10 ksi) o × 11 15 x diameter d. 1 in. is encased by a brass tube (E, 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 σ, 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.
