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

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 socket extension (2) has a diameter of 0.47 in. and a length of L = 1.5 in. It connects socket (3) to ratchet handle (1) which is 6.7 in. long. If a perpendicular force of 15 lb is applied to the end of the ratchet handle, determine the maximum shear stress in the socket extension.

A steel socket extension (2) has a diameter of 0.48 in. and a length of L = 1.8 in. It connects socket (3) to ratchet handle (1) which is 7.3 in. long. If a perpendicular force of 19 lb is applied to the end of the ratchet handle, determine the maximum shear stress in the socket extension.

A steel socket extension (2) has a diameter of 0.48 in. and a length of L = 5.0 in. It connects socket (3) to ratchet handle (1), which is 6.8 in. long. If a perpendicular force of 11 lb is applied to the end of the ratchet handle, determine the socket extension’s angle of twist.

How much heat is absorbed by a 20 (kg) of water when its temperature rises from 10 (0C) to 95 (0C)? The specific heat capacity of water is 4180 (J/Kg0C)

A steel socket extension (2) has a diameter of 0.50 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 17 lb is applied to the end of the ratchet handle, determine the maximum shear stress in the socket extension.

A steel socket extension (2) has a diameter of 0.46 in. and a length of L = 4.0 in. It connects socket (3) to ratchet handle (1), which is 7.0 in. long. If a perpendicular force of 11 lb is applied to the end of the ratchet handle, determine the socket extension’s angle of twist.

A steel 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 dump truck axle with a diameter of 1.78 in. and a length of 38 in. failed while transmitting a power of 485 hp and a torque of 8,030 lb-ft. At what speed was the axle spinning when it broke?
