A radial load of 6.5 kN is applied on a cylindrical roller bearing. The desired life of the bearing with 90% reliability is 18000 hours with the application factor 1.7. if the shaft rotates at 1600 rpm, then the required basic dynamic load rating for the bearing is given by:
1
103.4 MN
2
103.4 kN
3
1.042 kN
4
10.34 kN
