A crankshaft journal bearing in an automobile engine is lubricated by SAE 30 oil at 210°F. The bearing diameter is 3 in., the diametral clearance is 0.0025 in., and the shaft rotates at 3600 rpm; it is 1.25 in. long. The bearing is under no load, so the clearance is symmetric. Determine the torque required to turn the journal and the power dissipated.Given: Journal bearing, as shown. Note that the gap width, a, is half the diametral clearance. Lubricant is SAE 30 oil at 210°F.Speed is 3600 rpm.F
