WebA full Journal bearing 100 mm in diameter and 100 mm long has to support a radial load of 10 kN at an operating speed of 600 rpm. The radial clearance is 0.2 mm and the eccentricity is 0.15 mm. The resulting coefficient of friction value is 0.005. The viscosity of the oil used is 25 centi-poise. The Sommer field number is Solution WebOct 9, 2005 · " Friction can't do positive work, because: (1) In the case of kinetic friction: Kinetic friction always oppose motion so W = F*d*cos (x>90 degrees) = - F*d (2) In the case of static friction: Their is no displacement and therefore no work is done. Note: Friction can aid motion, as is the case when you are driving. " WebAug 22, 2024 · Did you know that your cycle breaks, sports shoes, and a matchstick are related?
