A composite beam is made of two brass [E = 119 GPa] plates bonded to an aluminum [E = 61 GPa] bar, as shown. The beam is subjected to a bending moment of 1670 N-m acting about the z axis. Assume b=44 mm, d1=30 mm, d2=9 mm. Determine: (a) the maximum bending stresses obr, Gat in the brass plates and the aluminum bar. (b) the stress in the brass obrj at the joints where the two materials are bonded together.
