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 0.244 in. and a length of L = 4.00 in. The shear modulus of the steel is G = 11,400 ksi. Determine the magnitude of the angle of twist of the shaft in degrees.

A dump truck axle with a diameter of 1.76 in. and a length of 36 in. failed while transmitting a power of 540 hp and a torque of 6,960 lb-ft. At what speed was the axle spinning when it broke?

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 = 21.4 N·m, TB = 31.9 N·m, TC = 10.7 N·m, TD = 32.1 N·m, and TE = 31.9 N·m.

A load of P = 11 N is applied to a hex wrench that has lengths a = 35 mm and b = 105 mm. Determine the torque applied to the set screw.

The solid circular steel shaft of a screwdriver is subjected to torque T. The shaft has a diameter of 0.460 in. and a length of L = 3.50 in. For a factor of safety of 1.8 and a shearing yield strength of 18 ksi, determine the maximum torque T that can be applied to the shaft.

A dump truck axle with a diameter of 1.61 in. and a length of 38 in. failed while transmitting a power of 505 hp and a torque of 5,260 lb-ft. At what speed was the axle spinning when it broke?

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 0.228 in. and a length of L = 4.25 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 torque of 23 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 0.0312 in.4 and a shear modulus of 180 ksi. The inner tube has a polar moment of inertia of 0.00667 in.4 and a shear modulus of 160 ksi. Determine the magnitude of the torque produced in the inner tube.

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 0.859 N·m is applied to gear D, determine the torque at gear A.

A dump truck axle with a diameter of 1.614 in. and a length of 37.1 in. failed when the shear stress reached 74 ksi on the outer surface. The shear modulus of the steel is G = 11,500 ksi. Assuming the shaft did not yield prior to failure, determine the angle of twist of the axle when it failed.
