Question

A composite beam is made of two brass [E = 95 GPa] plates bonded to an aluminum [E = 75 GPa] bar, as shown. The beam is subjected to a bending moment of 1480 N-m acting about the z axis. If the moment of inertia about the z axis of the equivalent all-aluminum beam is 629722 mm4, find the maximum bending stress in the aluminum plate.
