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 = 320 lb/in., a = 0.875 in. and b = 1.375 in. The reaction forces for this beam are Ay = Dy = 220 lb (both upward).

An aluminum [E = 7,450 ksi] bar is bonded to a steel [E = 34,600 ksi] bar to form a composite beam as shown. Find the distance to the centroid of the transformed section from the bottom surface of the beam.

An aluminum [E = 14,620 ksi] bar is bonded to a steel [E = 34,650 ksi] bar to form a composite beam as shown. The composite beam is subjected to a bending moment of M = +206 lb-ft about the z axis. If the centroid of the equivalent all-aluminum beam is 0.602 in. above the bottom surface of the beam, and the moment of inertia about the z axis of the equivalent all-aluminum beam is 0.1845 in.4, find the magnitude of the maximum bending stress in the steel.

For the shape shown, b = 16 in. and d = 5 in. Calculate the vertical distance from point H to the z centroidal axis.

An aluminum [E = 13,570 ksi] bar is bonded to a steel [E = 29,950 ksi] bar to form a composite beam as shown. The composite beam is subjected to a bending moment of M = +442 lb-ft about the z axis. If the centroid of the equivalent all-aluminum beam is 0.594 in. above the bottom surface of the beam, and the moment of inertia about the z axis of the equivalent all-aluminum beam is 0.1791 in.4, find the magnitude of the maximum bending stress in the steel.

If w = 5.75 in., find the moment of inertia about the z axis. The centroid of the section is located 2.6520 in. above the bottom surface of the beam.

If w = 7.75 in., find the moment of inertia about the z axis. The centroid of the section is located 2.8008 in. above the bottom surface of the beam.

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 = 280 lb/in., a = 1.000 in. and b = 1.125 in. The reaction forces for this beam are Ay = Dy = 157.5 lb (both upward).

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 = 320 lb/in., a = 0.875 in. and b = 1.125 in. The reaction forces for this beam are Ay = Dy = 180 lb (both upward).

Two identical beams are loaded with w on opposite ends. Which beam will have the bending stress with the largest magnitude?
