A single-row ball bearing has a radial load of 200 lb during operation. At this load, the bearing has an L10 life of 4200 revolutions. To extend the L10 life of the bearing to 10500 revolutions, the radial load must be lowered to: a) 146.984 lb b) 147.361 lb c) 147.689 lb d) 147.964 lb e) 148.302 Ib f) 148.556 Ib
