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.

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?
