A steel [E = 30,200 ksi, G = 11,600 ksi] socket extension (2) has a diameter of 0.32 in. and a length of L = 1.8 in. It connects socket (3) to ratchet handle (1) which is 4.5 in. long. If a perpendicular force of 9.0 lb is applied to the end of the ratchet handle, determine the socket extension’s angle of twist.

A torque of 25 lb·in. is applied to one end of a 7-in.-long composite shaft that consists of two polymer tubes. The outer tube has a polar moment of inertia of 0.0325 in.4 and a shear modulus of 165 ksi. The inner tube has a polar moment of inertia of 0.00169 in.4 and a shear modulus of 190 ksi. Determine the magnitude of the torque produced in the inner tube.

The solid circular steel shaft of a screwdriver is subjected to torque T. The shaft has a diameter of 0.451 in. and a length of L = 4.25 in. For a factor of safety of 2.0 and a shearing yield strength of 16 ksi, determine the maximum torque T that can be applied to 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 = 15.6 N·m, TB = 33.0 N·m, TC = 19.8 N·m, TD = 30.8 N·m, and TE = 28.4 N·m.

A load of P = 17 N is applied to a hex wrench that has lengths a = 44 mm and b = 165 mm. Determine the torque applied to the set screw.

A dump truck axle with a diameter of 1.77 in. and a length of 37 in. failed while transmitting a power of 410 hp and a torque of 7,890 lb-ft. At what speed was the axle spinning when it broke?

A load of P = 10 N is applied to a hex wrench that has lengths a = 22 mm and b = 82 mm. Determine the torque applied to the set screw.

A steel [E = 30,200 ksi, G = 11,700 ksi] socket extension (2) has a diameter of 0.33 in. and a length of L = 2.0 in. It connects socket (3) to ratchet handle (1) which is 4.6 in. long. If a perpendicular force of 6.0 lb is applied to the end of the ratchet handle, determine the maximum shear stress in the socket extension.

A torque of 22 lb·in. is applied to one end of a 5-in.-long composite shaft that consists of two polymer tubes. The outer tube has a polar moment of inertia of 0.031 in.4 and a shear modulus of 180 ksi. The inner tube has a polar moment of inertia of 0.00451 in.4 and a shear modulus of 160 ksi. Determine the magnitude of the torque produced in the outer tube.

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.
