A 36-lb cardboard box sits on an oak beam. Determine the maximum bending moment in the beam if the weight is modeled as distributed load w = 1.3846 lb/in. Let a = 36 in. and b = 26 in.

Determine the magnitude of the largest bending moment (consider both positive and negative peaks) in the beam. Let M = 114 lb·ft, a = 2.9 ft, and b = 8.1 ft. Assume the beam cannot lift off of the supports.

A load of P = 13 N is applied to a hex wrench that has lengths a = 40 mm and b = 136 mm. Determine the torque applied to the set screw.

A load of P = 77 N is applied a = 110 mm from the center of a 9 mm bolt. Determine the torque applied to the bolt.

A torque of T = 395 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 25 ksi.

A torque of TC = 910 N·m is applied to the aluminum shaft. Segment (1) has a diameter of 82 mm, and segment (2) has a diameter of 41 mm. Determine the angle of twist at C. Let L1 = 0.55 m and L2 = 0.32 m.

Determine the magnitude of the largest bending moment (consider both positive and negative peaks) in the beam. Let M = 133 lb·ft, a = 2.5 ft, and b = 9.5 ft. Assume the beam cannot lift off of the supports.

Gear B has 8 teeth, and gear C has 18 teeth. If a torque of 18 lb·in. and a speed of 1,980 rpm is required at A, determine the minimum power that the motor must provide.

Determine the magnitude of the largest bending moment (consider both positive and negative peaks) in the beam. Let M = 174 lb·ft, a = 2.6 ft, and b = 7.4 ft. Assume the beam cannot lift off of the supports.

Gear A has a diameter of 1.64 in., and gear B has a diameter of 2.31 in. If the pointer needs to be rotated 61° CW, how much should the motor be rotated?
