Question

leaf spring in an automobile is subjected to cyclic stresses. The average stress = 150 MPa; variablestress = 500 MPa; ultimate stress = 630 MPa; yield point stress = 350 MPa and endurance limit = 150MPa. Estimate, under what factor of safety the spring is working, by Goodman and Soderberg form
