Refer to the graph above. The government imposes an excise tax on gasoline. Consumers pay ____ of this tax, and sellers pay ____ of this tax.

Determine the reaction moment at A. Let w = 5 lb/in., a = 118 in., and EI = 41 × 106 lb·in.2.

Three 15-lb boxes are placed on an oak beam. Determine the vertical reaction force at the right end of the beam. Let a = 60 in. and b = 32 in.

Five toy blocks are glued together to form a beam that supports a shear force of 174 N. Each block has dimensions a = 19 mm and b = 57 mm. Determine the horizontal shear stress in the glue between blocks (2) and (3).

A cylindrical beam supports a shear force of 10.7 kN. The outside diameter is 48 mm, and the wall thickness is 6 mm. Determine the maximum horizontal shear stress in the beam.

Loads P = 849 N and Q = 397 N act on an oak beam. Determine the magnitude of the largest shear force (consider both positive and negative values) in the beam. Let a = 0.5 m and b = 1.5 m.

TRUE OR FALSE: Empirical studies (meaning, “real-world data”) have found strong evidence that tariffs reduce overall unemployment in the economy.

A cylindrical beam supports a shear force of 15.5 kN. The outside diameter is 44 mm, and the wall thickness is 5 mm. Determine the maximum horizontal shear stress in the beam.

Three 25-lb boxes are placed on an oak beam. Determine the vertical reaction force at the left end of the beam. Let a = 70 in. and b = 36 in.

Loads P = 667 N and Q = 376 N act on an oak beam. Determine the magnitude of the largest shear force (consider both positive and negative values) in the beam. Let a = 0.4 m and b = 0.7 m.
