Which scenario will result in the smallest bending moment in the beam?

A baby elephant lays on a cantilever beam causing its weight to act like a uniformly distributed load of 65 lb/ft. Determine the reaction moment at the right end of the beam. Let a = 3.1 ft and b = 4.4 ft.

Force P = 25 lb is applied to a wench that has dimensions a = 7.2 in., b = 0.73 in., and c = 0.15 in. Determine the magnitude of the largest bending stress in the handle of the wrench.

Which scenario will result in the largest bending moment in the beam?

A baby elephant lays on a cantilever beam causing its weight to act like a uniformly distributed load of 52 lb/ft. Determine the reaction moment at the right end of the beam. Let a = 2.1 ft and b = 4.2 ft.

Three toy blocks are stacked to form a channel shape. Each block has dimensions a = 11 mm and b = 33 mm. Determine the vertical distance from the table to the centroid of the shape.
