A square plate having 2.75 lb/in.2 weight has a circular hole. Along the right-hand edge of the plate, a circular cross-sectional rod having 0.75 lb/in. weight is welded to it. Determine the x position of the center of gravity. The x location of the center of gravity is in.

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.
