Use the graphical method to construct the shear-force and bending moment diagrams and identify the magnitude of the largest bending moment (consider both positive and negative peaks). Use w = 330 lb/in., a = 1.000 in. and b = 1.250 in. The reaction forces for this beam are Ay = Dy = 206.25 lb (both upward).

An aluminum [E = 7,880 ksi] bar is bonded to a steel [E = 31,850 ksi] bar to 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.

If M = 7.5 kip-ft, find the magnitude of the bending stress at a point 1.56 in. above the bottom surface of the beam. The moment of inertia about the z axis is 124.9 in.4, and the centroid of the section is located 4.7 in. above the bottom surface of the beam.
