Question

1. As part of their lab course, engineering students subjected a tensile test specimen to increased loads until it fails. The specimen has a gage length of 2.0" and a diameter of .5". However, they were not particularly careful about using consistent units. Based on the data shown in the table below, determine: a. The Young's modulus of the material b. The 0.2% yield strength c. The proportional limit Note: You may use Excel or Matlab. You must attach your graphs to your assignment and explain your procedure for finding the requested values. Load (kN) Change in length (mm) 0 0 7.6 0.02 14.9 0.04 22.2 0.06 28.5 0.08 29.9 0.10 30.6 0.12 32.0 0.16 33.3 0.20 36.8 0.24 41.0 0.50
