(5 points) You are choosing bearings for a shaft spinning at 600 RPM. You choose 02 Deep Grove Ball Bearings with a Bore of 65 mm and an OD of 120 mm. The shaft has a helical gear on it, which produces an axial loading of 1,904 N and a radial loading of 2,500 N. The bearing’s outer ring is spinning while the inner ring is stationary.  Calculate the of the bearing. Report your answer as an integer in hours.
