A shaft is subjected to a maximum load of 10 kN. It is designed to withstand a load of 15 kN. If the maximum load encountered is normally distributed with a standard deviation of 2.5 kN, and if shaft strength is normally distributed with a standard deviation of 2.0 kN, what failure percentage would be expected?
