Solved: A full journal bearing has a shaft journal

Chapter 12, Problem 12-6

(choose chapter or problem)

A full journal bearing has a shaft journal diameter of 25 mm with a unilateral tolerance of 20.01 mm. The bushing bore has a diameter of 25.04 mm with a unilateral tolerance of 0.03 mm. The l/d ratio is unity. The bushing load is 1.25 kN, and the journal rotates at 1200 rev/min. Analyze the minimum clearance assembly if the average viscosity is \(50 mPa \cdot s\) to find the minimum oil film thickness, the power loss, and the percentage of side flow.
