A load of P = 8 N is applied to a hex wrench that has lengths a = 24 mm and b = 85 mm. Determine the torque applied to the set screw.

The same perpendicular force is applied to the handles of three ratchets and creates torque. They have the same modulus of rigidity but different lengths and diameters. Which one will provide the smallest torque?

A torque of 27 lb·in. is applied to one end of a 6-in.-long composite shaft that consists of two polymer tubes. The outer tube has a polar moment of inertia of 0.0342 in.4 and a shear modulus of 185 ksi. The inner tube has a polar moment of inertia of 0.00563 in.4 and a shear modulus of 180 ksi. Determine the magnitude of the torque produced in the outer tube.

A dump truck axle with a diameter of 1.60 in. and a length of 36 in. failed while transmitting a power of 530 hp and a torque of 5,430 lb-ft. At what speed was the axle spinning when it broke?

A load of P = 17 N is applied to a hex wrench that has lengths a = 33 mm and b = 119 mm. Determine the torque applied to the set screw.

A steel [E = 30,200 ksi, G = 11,600 ksi] socket extension (2) has a diameter of 0.49 in. and a length of L = 1.8 in. It connects socket (3) to ratchet handle (1) which is 7.1 in. long. If a perpendicular force of 20 lb is applied to the end of the ratchet handle, determine the maximum shear stress in the socket extension.

A gear train is composed of four gears, where gears A and B are on the same shaft. Gear A has 60 teeth, gear B has 36 teeth, gear C has 48 teeth, and gear D has 12 teeth. If a torque of 1.17 N·m is applied to gear A, determine the torque at gear D.

A steel [E = 30,200 ksi, G = 11,900 ksi] socket extension (2) has a diameter of 0.49 in. and a length of L = 5.0 in. It connects socket (3) to ratchet handle (1), which is 6.5 in. long. If a perpendicular force of 12 lb is applied to the end of the ratchet handle, determine the socket extension’s angle of twist.

A baby-swing motor provides 0.29 W at 5,700 rpm to a shaft that has a diameter of 2.06 mm and a length of 14.3 mm. Determine the maximum shear stress in the shaft.

A solid constant-diameter shaft is subjected to the torques shown. Determine the absolute value of the internal torque in segment (2) of the shaft. Assume that TA = 23.2 N·m, TB = 31.0 N·m, TC = 19.7 N·m, TD = 39.2 N·m, and TE = 27.3 N·m.
