Problem 2:
The following chart shows test data from uniaxial tensile test. For it, determine the
following:
* Estimate the Young's Modulus of the material.
* Show on the chart above when the material has approximately yielded (i.e., what is
the yield stress of the material).
* If the material was rectangular in cross-section with dimensions of 0.003 inches by
0.156 inches, what is the tensile force at yielding.
