The graph below shows three constant reliability contours on a radial load vs$.$ life plot for a ball bearing. Both the $\backslash ($ x $\backslash )$ and $\backslash ($ y $\backslash )$ axes are in a logarithmic scale.

Which ONE of the three contours on the graph has the highest reliability?

Contour $1$

Contour $2$

Contour $3$

All contours are at the same reliability level.

QUESTION $2$

For the graph shown in Question $1,$ the bearing reliability at point B can be defined as the probability that the bearing life is equal to or longer than $\backslash ($ L$\_\{$B$\}\backslash )$ under radial load $\backslash ($ C$\_\{10\}\backslash ).$

True

False
