Consider the basic structure shown in the figure. First, thinking back to Newton's laws, describe the equilibrium condition that occurs at the grips. Next, The aluminum test specimen shown is subject to two equal and opposite centric axial forces of magnitude P.

(a) Calculate stress and strain, then plot the data for analysis.

(b) Mark yield and tensile strength on your plot and determine the modulus of elasticity for the test material given crosshead and extensometer data.

(c) Contrast and compare the plotted modulus obtained by the two data sets (what's different or the same about the two data sets). Explain how each data set could be used for the determination of the material's modulus of elasticity.
