A round cross-sectional bar d= 30 mm is cut from steel of Sut = 715 MPa. The bar is loaded with a completely reversed stresses. What is the strength of failure (in MPa) If only 10 4 cycles are needed? (Take fully corrected Se = 338 MPa, no need to use modification fcactors) (accepted answer range +/- 5 MPa)
