A steel rolling element bearing hascylindrical rolling elements that have radiiof 5 mm and are 10 mm long. If the normalload is 2000 N, calculate the rolling frictioncoefficient, assuming a fractional energyloss of 0.02.Now assume that the same cylindricalelements described in the problem aboveare sliding on the fixed flat surface. If thesliding speed of the cylinder is 0.25 m/s,calculate the average flash temperaturerise, assuming a sliding friction coefficientof 0.3.
