Determine the bearing life, in days, for a 30 mm bore diameter medium duty radial ball bearing supporting a shaft at A. The shaft operates at 630 rpm, 8-hours a day, everyday of the year. Assume the medium duty radial ball bearing is under uniform load and under a reliability requirement of 90%. Set T = 3.4 kN.
