mechanical design A machined steel rod is subjected to a repeated axial load of (180 kN). Find the diameter of the rod for a factor of safety of (2). Neglect column action. The material used to manufacture the rod is AISI 4140 Normalized. Let the fatigue stress concentration factor equal to unity. Make any necessary assumptions. If the loading was changed from repeated to completely reversed, what will be the new diameter? Which case is worse? Explain your answer. pls solve fast
