a round steel alloy bar with a diameter of 0.75 in and a gauge length of 3.0 in was subjected to tension, with the results shown in the accompanying table. using a computer spread sheet program, plot the stress-strain relationship. from the graph, determine the young's modulus of the steel alloy and the deformation corrsponding to a 8225 lb load.
load(lb) Deformation 10^-4 in.
