A load test on a 4.5-mm-diameter by 125-mm-long magnesium alloy rod found that a tension load of 831 N caused an elastic elongation of 0.47 mm in the rod. Using this result, determine the elastic elongation that would be expected for a 16-mm-diameter rod of the same material if the rod were 1.6 m long and subjected to a tension force of 3.3 kN.
