What is the biggest expectation when engineers test out designs? A.
Designs need to be totally unique.

B.
There are no expectations about the results, since all ideas are considered.

C.
Designs need to be feasible.

D.
Designs should be implemented within a certain time frame.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

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.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.
