Q1:

The life of a ball bearing is inversely proportional to

A (load)1

B (load)2

C (load)3

D (load)0.33

ANS:C - (load)3

This means that as the load on the ball bearing increases, its life decreases significantly. The relationship is cubic, meaning that if the load doubles, the life of the bearing decreases by a factor of eight. Conversely, if the load is halved, the life of the bearing increases by a factor of eight. This relationship underscores the importance of considering the operating conditions and load requirements when selecting ball bearings for a specific application.
