Your task is to design a full journal bearing to support the crankshaft of an engine. The crankshaft would be attached a journal that would be rotating within the bushing. The maximum speed of rotation of the crankshaft is 6000 rpm. The operating temperature is 130-F. The load on the bearing is 675lbf. The journal diameter has to fit on the crankshaft and has to be 2.5in. The length of the bearing has to be under 1.5in. The oil used in the engine is SAE 50. The performance of your bearing should have a maximum coefficient of friction of 0.04 and a minimum film thickness no lower than 0.001in. Determine the bearing dimensions you will use based on your goals and the charts in your formula sheet.
