1.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.
2000 11.28
4000 22.54
6000 33.80
8000 45.08
10000 56.36
12000 67.66
Is the deformation equal to the strain? Or do I have to do: (3-0.001128)/3...etc?
