Question: given the bar shown has a rectangular cross section and...

Question details

Given: The bar shown has a rectangular cross section and is cyclically loaded with a tension force, P- 5000 lb. at an operating temperature of 100°F. It is planned to make the bar out of AISI 1018 cold-drawn steel. Assume the notch sensitivity is g 0.8. 1.S -> P : 5000 lb a) Write a program in MS Excel to estimate the endurance limit of the bar if the fillet radius, r, is 0.06 inches. Include in your program the routines to calculate each modifier and the final endurance limit (Se) Find: If the fillet radius, r, is increased to 0.175 inches, determine the following: b) c) Estimate the endturance limit of the bar Prescribe a minimum thickness, t, for the bar to predict infinite life.
