A composite beam is made of two brass [E = 97 GPa] plates bonded to an aluminum [E = 62 GPa] bar, as shown. The beam is subjected to a bending moment of 1690 N-m acting about the z axis. Assume b=61 mm, d,=47 mm, d2=10 mm. Determine: (a) the maximum bending stresses opr, oat in the brass plates and the aluminum bar. (b) the stress in the brass oprj at the joints where the two materials are bonded together. Brass (2) Aluminum (1) Brass (2) d2 b Answers: (a) obr MPa, ogl MPа.
