Question: Consider the leaf spring experiment in Exercise 14 9 Suppose that
Consider the leaf spring experiment in Exercise 14.9. Suppose that factor E (quench oil temperature) is very difficult to control during manufacturing. We want to have the mean spring height as close to 7.50 as possible with minimum variability. Where would you set factors A, B, C, and D to reduce variability in free height as much as possible regardless of the quench oil temperature used?
