Chapter 2, problem 2/028 the 235000-lb space-shuttle orbiter touches down at about 231 mi/hr. at 210 mi/hr its drag parachute deploys. at 39 mi/hr, the chute is jettisoned from the orbiter. if the deceleration in feet per second squared during the time that the chute is deployed is -0.00030v2 (speed v in feet per second), determine the corresponding distance s traveled by the orbiter. assume no braking from its wheel brakes.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

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.
