Consider the 1040 carbon steel listed in the table below. A 20-mm-diameter bar of this alloy is used as a structural member in an engineering design. The unstressed length of the bar is precisely 1 m. The structural load on the bar is 1.6A????110^5N in tension. What will be the length of the bar under this structural load?
