Question

Hi I need Stress Strain Graphs to be made for the following data tables. There should be 3 graphs, one for each table. I also need to know what material each sample is made of. I assume this is calculated from calculating the Modulus of Elasticity E. However I do not really know. I appreciate everything. There is an image of the tables as well as the data itself below this post.

Include the Following

• Stress Strain graphs for each sample showing what variable and unit you have on both axes, and stating if it is sample 1, 2 or 3. Show the points in the graph and additionally a trendline.
• Explain how you got your conclusion (i.e., show your work) including how it was calculated/how you got it, what value it had and what you compared with.
• Your conclusion of what each of the three samples are made of.
