A 3-inch diameter shaft rotates at 750 rev/min in a 3-inch-long full journal bearing. The lubricant sump has a steady-state temperature of 100F. Analyze the assembly assuming average clearance and a H8/f8 clearance fit. The maximum lubricant temperature must not exceed 200F. Determine the following (you may modify and use the MATLAB script provided in Blackboard for the example problem): a. If SAE Grade 20 lubricant is used, find the maximum radial load that the journal can carry and still operate under thick-film lubrication conditions, i.e., the minimum film thickness: ho 6.3 10 in. What is the corresponding total lubricant volumetric flow rate and the power loss? (5 points) b. Find the maximum radial load that the journal can carry and still operate under thick-film lubrication conditions if SAE Grade 30 lubricant is used. What is the corresponding maximum oil-film pressure and its angular location? (5 points)
