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.

Determine the reaction force at B. Let w = 15 lb/in., a = 67 in., and EI = 58 × 106 lb·in.2.

Refer to the graph above. The government imposes a $40 price ceiling in the market for sweaters. As a result, ____ will be bought and sold. 

Determine the deflection at C. Let M = 6,500 lb·in., a = 69 in., b = 33 in., and EI = 106 × 106 lb·in.2.

Determine the deflection at C. Let w = 12 lb/in., a = 94 in., b = 24 in., and EI = 90 × 106 lb·in.2.

Determine the deflection at C. Let P = 170 lb, a = 128 in., b = 32 in., and EI = 166 × 106 lb·in.2.

TRUE OR FALSE: Empirical studies (meaning, “real-world data”) have shown that historical increases in the minimum wage led to large increases in unemployment.
