3. A full journal bearing has a journal diameter of 3 in. The bushing bore has a diameter of 3.005 in. The bushing is 1.5 in long. The load is 800 lbf and the journal runs at 600 rev/min. For (a) SAE 10 and (b) SAE 40 lubricants, find the minimum film thickness and the maximum film pressure for an operating temperatures of 150°F for the minimum clearance assembly.
