A machine part is subjected to fluctuating simple, multiaxial stresses. The fully corrected nonzero stress ranges are: \( \sigma_{x \min }=20 \mathrm{MPa} \), \( \sigma_{x \max }=150 \mathrm{MPa}_{,} \sigma_{y \min }=30 \mathrm{MPa} \). Using a Case 3 load line, calculate the infinite-life safety factor given by von Mises method. \( \sigma_{y \max }=100 \mathrm{MPa}, \tau_{x y \min }=60 \mathrm{MPa} \) Express your answer to three significant figures. \( \tau_{x y \max }=150 \mathrm{MPa} \), The material properties are: \( S_{\mathrm{e}}=620 \mathrm{MPa} \) and \( S_{u t}=1390 \mathrm{MPa} \).
