An 02-series single-row deep-groove ball bearing with a 65-mm bore (see Tables 11–1 and 11–2 for specifications) is loaded with a 3-kN axial load and a 7-kN radial load. The outer ring rotates at 500 rev/min.

(a) Determine the equivalent radial load that will be experienced by this particular bearing.
(b) Determine whether this bearing should be expected to carry this load with a 95 percent reliability for 10 kh.
