Problem 1 A material is tested for cyclic fatigue failure whereby a stress, in MPa, is applied to the material and the number of cycles needed to cause failure is measured. The results are in the table below. When a log-log plot of stress versus cycles is generated, the data trend shows a linear relationship. Use least-squares regression to determine a best-fit equation for these data 100 1.000 10,000 100,000 I1.000,000 N, cycles 10 Stress, MPa 1001000925 800625 550 420
