It is required to find the bore diameter of a single disc clutch, that transmits 7 HP from an engine. The contact pressure is 1 MPa, the coefficient of friction is 0.3, the outer radius is 45 mm, and the rotational speed is 1500 rpm.

What precautions should you take to prevent injuries when dealing with heavy loads?

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

Asimple rankine cycle uses water as the working fluid. the water enters the turbine at 10 mpa and 480c while the condenser operates at 6 kpa. if the turbine has an isentropic efficiency of 80 percent while the pump has an isentropic efficiency of 70 percent determine the thermal efficiency
