Question: Develop the expression for fatigue strength as a function of number of cycles for a 3 2 mm diameter machined rod under non - rotating

Develop the expression for fatigue strength as a function of number of cycles for a 32 mm diameter machined rod under non-rotating bending. The steel has a tensile strength of 710 MPa and a fully corrected endurance limit of Se=265 MPa. The fatigue strength fraction, (f) can be taken as 0.84.
