11.6 A hardened and ground steel journal which is 49,99 mm in diameter rotates in a bronze bearing 50 mm in diameter at a speed of 1 200 r/min. The bearing is 30 mm long. Under constant loading conditions, deter- mine the probable coefficient of friction and maximum radial load and power loss if hydrodynamic lubrication is to be maintained. The following assumptions may be made: Viscosity grade of oil = ISO VG 22; density
883 kg/mº; ambient temperature 25°C; and bearing temperature = 55°C. [u = 0,009 1;2069 N;59,1 W gyerase unyenn- for to an
