For that same cycle, the stress amplitude and mean stress are
Answer: D
Correct answer: 40 and 60 MPa
\[ \sigma_a = \frac{100-20}{2} = 40\ \mathrm{MPa}, \qquad \sigma_m = \frac{100+20}{2} = 60\ \mathrm{MPa}. \] The amplitude is half the range and the mean is the average of the extremes. Together with the range and the ratio, any two of these four quantities fix the cycle completely.
