Four toy blocks are stacked to form a hollow-rectangular-tube shape. Each block has dimensions a = 22 mm and b = 66 mm. Determine the moment of inertia about the horizontal centroidal axis for the shape.

Two toy blocks are stacked to form a tee-shape. Each block has dimensions a = 23.5 mm and b = 70.5 mm. Determine the vertical distance from the table to the centroid of the shape.

A baby elephant lays on a cantilever beam causing its weight to act like a uniformly distributed load of 55 lb/ft. Determine the reaction moment at the right end of the beam. Let a = 2.2 ft and b = 4.2 ft.

A 1,570-lb dinosaur stands on a simply-supported beam. Determine the maximum bending moment in the beam. Let a = 9.1 ft and b = 7.3 ft.

A piece of composite-lumber flooring is a = 78 mm wide. It consists of a layer of pine [E = 6.6 GPa] that is b = 18 mm thick and a layer of cherry [E = 9.4 GPa] that is c = 5 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 57 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.
