Amass of air occupying a volume of 0.15m^3 at 3.5 bar and 150 °c is allowed to expand isentropically to 1.05 bar. its enthalpy is then raised by 52kj (note the unit) by heating at constant pressure. assuming that all processes occur reversibly, sketch them on a p-v chart and calculate the total work done and the total heat transfer.

Which of the following is an easy way to remember the modified “x” tire rotation? a. nondrive wheels straight, cross the drive wheels b. drive wheels straight, cross the nondrive wheels c. drive wheels crossed, nondrive wheels straight d. drive wheels crossed, nondrive wheels crossed

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.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
