Question:

A full journal bearing has a journal diameter of 1.250 in, with a unilateral tolerance of −0.001 in. The bushing bore has a diameter of 1.252 in and a unilateral tolerance of 0.003 in. The bearing is 2.5 in long. The journal load is 400 lbf and it runs at a speed of 1150 rev/min. Using an average viscosity of 10 μreyn find the minimum film thickness, the maximum film pressure, and the total oil-flow rate for the minimum clearance assembly.
