Four toy blocks are stacked to form a hollow-rectangular-tube shape. Each block has dimensions a = 11 mm and b = 33 mm. Determine the moment of inertia about the horizontal centroidal axis for 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 = 3.1 ft and b = 4.6 ft.

A 2,550-lb dinosaur stands on a simply-supported beam. Determine the maximum bending moment in the beam. Let a = 10.7 ft and b = 7.2 ft.

A baby elephant lays on a cantilever beam causing its weight to act like a uniformly distributed load of 58 lb/ft. Determine the reaction moment at the right end of the beam. Let a = 3.4 ft and b = 5.1 ft.

A 2,240-lb robotic dinosaur stands on a simply-supported beam. Determine the vertical reaction force at the right end of the beam. Let a = 8.7 ft and b = 6.8 ft.

A 9.9-lb pterodactyl stands at a = 5.2 ft on a limb. Determine the maximum bending moment in the limb.

Two toy blocks are stacked to form a tee-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 snow drift acts like a linearly distributed load on the beam. Determine the vertical reaction force at the right end of the beam. Let w = 16.0 lb/ft, a = 5 ft, and b = 3 ft.
