A6-inch diameter shaft rotates inside a 6.03-ich diameter, 15 inch long sleeve at a speed of 60 rev/minute. the annular space between the shaft and the sleeve is filled with sae 30 oil at 86°f. calculate the power dissipated by fluid friction.

What precautions should you take to prevent injuries when dealing with heavy loads?

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
