A 25-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 = 1.2500 lb/in. Let a = 41 in. and b = 20 in.

Determine the magnitude of the largest bending moment (consider both positive and negative peaks) in the beam. Let M = 148 lb·ft, a = 2.6 ft, and b = 10.4 ft. Assume the beam cannot lift off of the supports.

Gear A has 77 teeth, and gear B has 59 teeth. If a torque of 34 lb·in. and a speed of 920 rpm is required at C, determine the minimum power that the motor must provide.

Gear A has a diameter of 1.72 in., and gear B has a diameter of 2.25 in. If the pointer needs to be rotated 47° CW, how much should the motor be rotated?

A 76-lb child and a 24-lb cardboard box are on an oak beam. Determine the vertical reaction force at the left end of the beam. Let a = 24 in., b = 34 in., and c = 48 in.

A load of P = 14 N is applied to a hex wrench that has lengths a = 41 mm and b = 143 mm. Determine the torque applied to the set screw.

A 70-lb child and a 25-lb cardboard box are on an oak beam. Determine the vertical reaction force at the right end of the beam. Let a = 24 in., b = 31 in., and c = 45 in.

A 66-lb child and a 18-lb cardboard box are on an oak beam. Determine the vertical reaction force at the right end of the beam. Let a = 24 in., b = 36 in., and c = 42 in.

Loads P = 90 N, Q = 95 N, and R = 39 N are applied to the structure. Determine the torque generated in segment (2). Let a = 117 mm, b = 75 mm, and c = 57 mm.

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.
