A full journal bearing is 25 mm long. The shaft journal has a diameter of 50 mm with a unilateral tolerance of −0.01 mm. The bushing bore has a diameter of 50.05 mm with a unilateral tolerance of 0.01 mm. The load is 2000 N and the journal speed is 840 rev/min. For the minimum clearance assembly find the minimum oil-film thickness, the power loss, and the side flow if the operating temperature is 55◦C and SAE 30 lubricating oil is used.
