For a given component, the alternating stress is equal to 250 MPa, Mean stress is 100 MPa, and the ultimate tensile strength is 500 MPa. Find the yield strength of the material according to Goodman’s approach?

For a given component, the alternating stress is equal to 250 MPa, Mean stress is 100 MPa, and the ultimate tensile strength is 500 MPa. Find the yield strength of the material according to Goodman’s approach? Correct Answer 312.5 MPa

According to Goodman’s approach the: σa= σe; where the x=1 So the equation becomes σa= σe Substituting the values in the equatio-> 250 = σe -> σe = 250*(5/4) -> σe = 312.5 MPa.
