The life (L) of a radially loaded spherical ball bearing can be estimated from equation (2) given below. Experimental testing of the mechanism has detemined that the average radial load that the bearing will be subjected to is F = 8.34 [kN] based on 6 repetitions of the test. If the rated load of the bearing is C = 8.25 [kN] and the life (in number of revolutions) at the rated load is given as LR = 9 x 107 [rev], determine the expected life of the bearing in revolutions [rev] and determine the total uncertainty of that result at 95% probability.

Suppose you're converting a bill of materials for machining feedstock from the British gravitational (U.S. system) of units to International System (SI) units. Your goal is to have all of the material quantities in kilograms. Your bill of materials lists values for required weights of brass rod in pounds. To convert to these values to kilograms you first you divide by gravitational acceleration in feet per second squared to get a mass in slugs, then convert slugs to kilograms using standard conversion factors.
