The 25-lb box slides on the surface for which = 0.25. The box has a velocity = 15 ft/s when it is 2 ft from the plate. If it strikes the smooth plate, which has a weight of 12 lb and is held in position by an unstretched spring of stiffness = 410 lb/ft, determine the maximum compression imparted to the spring. Take = 0.75 between the box and the plate. Assume that the plate slides smoothly.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
