An аluminum [E = 7,880 ksi] bаr is bоnded tо а steel [E = 31,850 ksi] bar tо form a composite beam as shown. The composite beam is subjected to a bending moment of M = +368 lb-ft about the z axis. If the centroid of the equivalent all-aluminum beam is 0.651 in. above the bottom surface of the beam, and the moment of inertia about the z axis of the equivalent all-aluminum beam is 0.2291 in.4, find the magnitude of the maximum bending stress in the steel.
