A brake assembly has been tested and found to have a capacity that is normally distributed with a mean of 275 lb and a standard deviation of 25 lb. If a normally distributed force having a mean of 180 lb and a standard deviation of 30 lb is applied, what is the static reliability? As the variability (variance) of either the strength or load ncreases, what happens to the reliability?
