A $02-55$ deep$-$groove ball bearing is used to support $5\mathrm{.}9$ kN of radial load and $2\mathrm{.}1$ kN of axial load. The inner ring of the bearing rotates at $3500$ rpm and the outer ring is fixed. Do the following:

Find the equivalent radial load on the bearing, $F_e=$ kN

For an application facor of $1\mathrm{.}2,$ find the life of the bearing in hours. Round$-$down your answer to the nearest hour.

$L_{hr}=$ hours

Assume reliability of $90\%$ for all your calculations.
