Young's Modulus and the Poisson Ratio of Aluminium

Homework Statement

Find Young's Modulus and Poisson Ratio of Aluminium from the set of values below

Relevant Equations

Young Modulus = (Axial Strain)/Tensile Stress

Hi. I've been given these sets of value. How do I calculate Young's modulus and Poisson Ratio from these set of value. I tried to create a stress vs strain graph but the graph does not look like a common stress vs strain graph but instead more of a y=x graph.

The diameter of the rod is 10mm and the material of this rod is aluminium. How do I make the longitudinal strain a value such that I can use it for the axial strain and make the transverse strain a value that can be used for the tensile stress?

What did you plot against what?
Please post the graph you obtained and explain in what way you think it does not resemble a stress/strain graph.
What distinction are you making between longitudinal strain and axial strain? Aren't they the same thing?

I don't understand your question about using transverse strain for tensile stress. A strain is not a stress. The bar is being placed under tension, as a result of which it lengthens (longitudinal strain) and narrows (transverse strain).

If you can, please post the raw data in a machine readable form so that others can create graphs from them.
What attempt have you made to find the Poisson ratio?
