A load of P = 13 N is applied to a hex wrench that has lengths a = 42 mm and b = 147 mm. Determine the torque applied to the set screw.

Blue-green light has a frequency of about 6 × 1014 Hz, what is the wavelength of this light in vacuum? speed of light in vacuum is 300,000,000 (m/s)?

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

The solid circular steel shaft of a screwdriver is subjected to a pure torque of T = 23 lb·in. The shaft has a diameter of 0.234 in. and a length of L = 3.75 in. The shear modulus of the steel is G = 11,300 ksi. Determine the magnitude of the angle of twist of the shaft in degrees.

A steel [E = 30,100 ksi, G = 11,500 ksi] socket extension (2) has a diameter of 0.62 in. and a length of L = 1.3 in. It connects socket (3) to ratchet handle (1) which is 9.0 in. long. If a perpendicular force of 24.0 lb is applied to the end of the ratchet handle, determine the maximum shear stress in the socket extension.

A torque of 26 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 0.037 in.4 and a shear modulus of 170 ksi. The inner tube has a polar moment of inertia of 0.00779 in.4 and a shear modulus of 180 ksi. Determine the magnitude of the torque produced in the inner tube.

Which would be the normal appearance of an ovary?

A steel [E = 30,500 ksi, G = 11,900 ksi] socket extension (2) has a diameter of 0.63 in. and a length of L = 1.0 in. It connects socket (3) to ratchet handle (1) which is 8.9 in. long. If a perpendicular force of 18.0 lb is applied to the end of the ratchet handle, determine the maximum shear stress in the socket extension.

A load of P = 14 N is applied to a hex wrench that has lengths a = 48 mm and b = 170 mm. Determine the torque applied to the set screw.

A torque of 27 lb·in. is applied to one end of a 4-in.-long composite shaft that consists of two polymer tubes. The outer tube has a polar moment of inertia of 0.0476 in.4 and a shear modulus of 170 ksi. The inner tube has a polar moment of inertia of 0.0188 in.4 and a shear modulus of 160 ksi. Determine the magnitude of the torque produced in the inner tube.
