1.	Define the fatigue limit of a metal.(a) Stress below which metal will endure an infinite number of cycles without fracture(b) Stress above which metal will endure an infinite number of cycles without fracture(c) Stress at which metal will endure a less finite number of cycles(d) Stress at which metal will endure a more finite number of cyclesThis question was posed to me during an interview.My question is taken from Eight Forms in chapter Eight Forms of Corrosion of Corrosion Engineering
Answer» The CORRECT choice is (a) STRESS below which metal will endure an infinite number of cycles WITHOUT fracture The best I can explain: Fatigue limit is the stress below which metal will endure an infinite number of cycles without fracture. The fatigue limit can be calculated by (SN CURVE) stress and the number of cycles curve.
