Gear A has 71 teeth, and gear B has 46 teeth. If a torque of 25 lb·in. and a speed of 870 rpm is required at C, determine the minimum power that the motor must provide.

A torque of TC = 750 N·m is applied to the aluminum shaft. Segment (1) has a diameter of 75 mm, and segment (2) has a diameter of 38 mm. Determine the angle of twist at C. Let L1 = 0.64 m and L2 = 0.32 m.

Gear A has a diameter of 1.55 in., and gear B has a diameter of 2.26 in. If the pointer needs to be rotated 133° CW, how much should the motor be rotated?

A torque of TC = 840 N·m is applied to the aluminum shaft. Segment (1) has a diameter of 71 mm, and segment (2) has a diameter of 39 mm. Determine the angle of twist at C. Let L1 = 0.67 m and L2 = 0.39 m.

Determine the magnitude of the largest bending moment (consider both positive and negative peaks) in the beam. Let M = 180 lb·ft, a = 3.1 ft, and b = 7.9 ft. Assume the beam cannot lift off of the supports.

A beam has dimensions of b = 18 in., h = 22 in., and d = 19.5 in. and is reinforced with 4 No. 5 bars. The concrete strength is 7,900 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the strength Mn for this beam.

A 21-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 = 21 lb. Let a = 53 in.

A load of P = 7 N is applied to a hex wrench that has lengths a = 27 mm and b = 97 mm. Determine the torque applied to the set screw.

Gear B has 8 teeth, and gear C has 17 teeth. If a torque of 10 lb·in. and a speed of 2,180 rpm is required at A, determine the minimum power that the motor must provide.

Gear A has a diameter of 1.04 in., and gear B has a diameter of 1.49 in. If the pointer needs to be rotated 66° CW, how much should the motor be rotated?
