Two blocks with masses m1=3.17kg, and m2=7.14kg hang from each other tied to the roof of an elevator, which rises with acceleration pointing upwards, of magnitude a=0.57m/s^2. for this problem, take the positive direction upwards, and use g=9.8m/s^2 as the magnitude of the acceleration due to gravity. obtain t2 in newtons

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.
