Chapter 20, Problem 52P
An experiment is performed to define the relationship between applied stress and the time to fracture for a type of stainless steel. Eight different values of stress are applied, and the resulting data are
Applied stress x,

5 | 10 | 15 | 20 | 25 | 30 | 35 | 40 |
Fracture time y, hr | 40 | 30 | 25 | 40 | 18 | 20 | 22 | 15 |
Plot these data and then develop a best-fit equation to predict the fracture time for an applied stress of
