A full journal bearing has a journal diameter of 38 mm, with a unilateral tolerance of -0.012 mm. The bushing bore has a diameter of 38.05 mm and a unilateral tolerance of 0.032 mm. The bearing is 76 mm long. The journal load is 1.9 kN, and the journal runs at 491.6898 rev/min. Using an average viscosity of 55.6 mPa-s, find the minimum film thickness, the maximum film pressure, and the total oil-flow rate for the minimum clearance assembly. The minimum film thickness is mm. The maximum film pressure is Mpa. The total oil-flow rate for the minimum clearance assembly is |mm3/s.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
