A 15-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 = 15 lb. Let a = 45 in.

A torque of TC = 910 N·m is applied to the aluminum [G = 71 GPa] shaft. Segment (1) has a diameter of 80 mm, and segment (2) has a diameter of 41 mm. Determine the angle of twist at C. Let L1 = 0.52 m and L2 = 0.37 m.

Gear A has 68 teeth, and gear B has 57 teeth. If a torque of 60 lb·in. and a speed of 860 rpm is required at C, determine the minimum power that the motor must provide.

Gear B has 10 teeth, and gear C has 18 teeth. If a torque of 16 lb·in. and a speed of 2,050 rpm is required at A, determine the minimum power that the motor must provide.

A 63-lb child and a 111-lb adult are on an oak beam. Determine the vertical reaction force at the right end of the beam. Let a = 26 in., b = 48 in., and c = 22 in.

A load of P = 29 N is applied a = 235 mm from the center of a 20 mm bolt. Determine the torque applied to the bolt.

A 35-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 = 1.4583 lb/in. Let a = 36 in. and b = 24 in.

A beam is singly reinforced with the reinforcement in two rows. The bottom row contains 10 No. 7 bars at a depth of 20 in. The top row contains 8 No. 8 bars at a depth of 14.5 in. Determine the effective (centroidal) depth, d, of the steel.

A torque of TC = 860 N·m is applied to the aluminum [G = 69 GPa] shaft. Segment (1) has a diameter of 76 mm, and segment (2) has a diameter of 40 mm. Determine the angle of twist at C. Let L1 = 0.64 m and L2 = 0.37 m.

Gear A has a diameter of 1.58 in., and gear B has a diameter of 2.18 in. If the pointer needs to be rotated 154° CW, how much should the motor be rotated?
