A piece of composite-lumber flooring is a = 68 mm wide. It consists of a layer of pine [E = 7.5 GPa] that is b = 19 mm thick and a layer of cherry [E = 10.8 GPa] that is c = 4 mm thick. Determine the distance to the centroid of the transformed section from the bottom of the board.

A 49-N eagle sits on a tee-shaped post that has a diameter of 47 mm. Determine the magnitude of the largest normal stress in the vertical part of the post. Let a = 0.45 m be the distance from the eagle to the centroid of the post.

Two toy blocks are stacked to form a tee-shape. Each block has dimensions a = 22.7 mm and b = 68.1 mm. Determine the vertical distance from the table to the centroid of the shape.

Two toy blocks are stacked to form an L-shape. Each block has dimensions a = 21.7 mm and b = 65.1 mm. Determine the vertical distance from the table to the centroid of the shape.

A baby elephant lays on a simply-supported beam causing its weight to act like a uniformly distributed load of 74 lb/ft. Determine the vertical reaction force at the right end of the beam. Let a = 2.6 ft and b = 4.0 ft.

Force P = 34 lb is applied to a wench that has dimensions a = 6.2 in., b = 0.72 in., and c = 0.25 in. Determine the magnitude of the largest bending stress in the handle of the wrench.

A 8.1-lb pterodactyl stands at a = 4.7 ft on a limb. Determine the maximum bending moment in the limb.
