Gear A has a diameter of 1.94 in., and gear B has a diameter of 2.70 in. If the pointer needs to be rotated 111° CW, how much should the motor be rotated?

A torque of T = 160 lb·in. is applied to two pulleys and a copper-alloy shaft. Determine the minimum diameter of the shaft if its shear yield strength is 19 ksi.

Determine the magnitude of the largest bending moment (consider both positive and negative peaks) in the beam. Let M = 149 lb·ft, a = 3.6 ft, and b = 10.4 ft. Assume the beam cannot lift off of the supports.

A 35-lb cardboard box sits on an oak beam. Determine the maximum bending moment in the beam if the weight is modeled as concentrated load P = 35 lb. Let a = 52 in.

A load of P = 20 N is applied to a hex wrench that has lengths a = 29 mm and b = 108 mm. Determine the torque applied to the set screw.

A beam has dimensions of b = 14 in., h = 28 in., d’ = 2.5 in., and d = 25.5 in. It is reinforced with 2 No. 5 bars on the compression side and 5 No. 8 bars on the tension side. The concrete strength is 3,400 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 6.026 in., determine the strain in the compression reinforcement, ε’s.
