Alift up system is used to transport objects among different floors. the two bearings on both ends of the shaft have the same dimension (l = 1 inch and diameter d = 2 inch), and they are made of steel-backed, ptfe coated bronze. the load bearing statistics are as follows: pmax = 36,000 psi; vmax = 390 ft/min; (pv)max = 51,000 lb-ft/in2-min. a cable is located at the midpoint of the shaft that is used to lift the chamber. the radius of the drum on the shaft is 6 inches. if the speed of the lifting chamber is 18 in/s, find the maximum load this lifting system can support.

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.
