2. A journal bearing 4 inches in diameter and 4 inches long has a radial clearance of 0.002 inches. It rotates at 2000 rpm and is lubricated with SAE 10 oil at 200F. In the following, use an applied load of 225 lbs and neglect temperature rise. a. Estimate the power loss and the friction torque using the Petrov equation. Calculate the coefficient of friction. b. Calculate the minimum clearance, the power loss, friction torque and the coefficient of friction
