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 = 20.0 N·m, TB = 34.4 N·m, TC = 22.5 N·m, TD = 39.1 N·m, and TE = 31.0 N·m.

A dump truck axle with a diameter of 1.72 in. and a length of 37 in. failed while transmitting a power of 465 hp and a torque of 6,660 lb-ft. At what speed was the axle spinning when it broke?

A steel socket extension (2) has a diameter of 0.49 in. and a length of L = 1.3 in. It connects socket (3) to ratchet handle (1) which is 7.0 in. long. If a perpendicular force of 15 lb is applied to the end of the ratchet handle, determine the socket extension’s angle of twist.

A solid constant-diameter shaft is subjected to the torques shown. Determine the absolute value of the internal torque in segment (3) of the shaft. Assume that TA = 17.4 N·m, TB = 48.4 N·m, TC = 11.7 N·m, TD = 44.0 N·m, and TE = 63.3 N·m.

A steel socket extension (2) has a diameter of 0.32 in. and a length of L = 2.3 in. It connects socket (3) to ratchet handle (1) which is 5.2 in. long. If a perpendicular force of 8.0 lb is applied to the end of the ratchet handle, determine the socket extension’s angle of twist.

A dump truck axle with a diameter of 1.729 in. and a length of 37.0 in. failed when the shear stress reached 70 ksi on the outer surface. The shear modulus of the steel is G = 11,300 ksi. Assuming the shaft did not yield prior to failure, determine the angle of twist of the axle when it failed.

A baby-swing motor provides 0.31 W at 5,700 rpm to a shaft that has a diameter of 2.41 mm and a length of 14.7 mm. Determine the maximum shear stress in the shaft.

The solid circular steel shaft of a screwdriver is subjected to a pure torque of T = 20 lb·in. The shaft has a diameter of 0.237 in. and a length of L = 3.50 in. The shear modulus of the steel is G = 11,600 ksi. Determine the magnitude of the angle of twist of the shaft in degrees.

A dump truck axle with a diameter of 1.70 in. and a length of 37 in. failed while transmitting a power of 420 hp and a torque of 6,030 lb-ft. At what speed was the axle spinning when it broke?

A torque of 22 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 0.0406 in.4 and a shear modulus of 180 ksi. The inner tube has a polar moment of inertia of 0.00779 in.4 and a shear modulus of 160 ksi. Determine the magnitude of the torque produced in the outer tube.
