A tensile test was performed on a metal specimen with a diameter of
1/2 inch and a gage length (the length over which the elongation is meas-
ured) of 4 inches. The data were plotted on a load-displacement graph,
P vs. AL. A best-fit line was drawn through the points, and the slope of
the straight-line portion was calculated to be P/AL = 1392 kips/in. What
is the modulus of elasticity?
