1kg of steam in a cylinder expands reversibly behind a piston according to the law pv=constant from 7 bar to 0.75 bar. if steam is initially dry saturated, find; 1.the final temperatures 2.the work done by the steam 3.the heat flow to or from the cylinder

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

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.
