, Plot on log-log coordinates estimated S-N curves for (a) bending, (b) axial, and (c) torsional loading of a 25 mm-diameter steel bar having Su = 760 MPa. Sy = 530 MPa, and machined surfaces. For each of the three types of loading, what is the fatigue strength corresponding to (1) 10° or more cycles, and (2)6 x 104 cycles? 1 [Partial ans.: For bending 36.6 ksi, 55 ksi]
