(a) What is the change in length of the bar? (b) What should be the additional magnitude to be added to load applied at D supposed the bar does not change in length? (c) Supposed the bar does not change in length, the applied load at D remains 1300 lb, and the areas for segment AB and BC remain 0.40 in?, determine the revised area for segment CD.
