A composite beam is made of two brass [E =101 GPa] plates bonded to an aluminum [E =64 GPa] bar, as shown in Figure below. The beam is subjected to a bending moment of 2030 N-m acting about the z axis. Assume b=53 mm, d1=52 mm, d2 =11 mm, Determine: (a)the maximum bending stresses in the brass plates and the aluminum bar. (b) the stress in the brass at the joints where the two materials are bonded together.
