You asked a lab to conduct a uniaxial tension test on a small specimen of a mystery material. The resulting conventional stress strain diagram is provided, along with dimensions of the cylindrical sample specimen that you provided the lab.

Mystery Material, Conventional Stress Strain Diagram 40 mm 100 120 strain,e (x 10-6 mm/mm) 6 mm 140 160 180 10 mm 200 A) Calculate the material's Modulus of Elasticity, E B) At the instant the stress reached 400 kPa, the lab paused the test, keeping load on the sample, they measured the sample's diameter with very precise calipers. The diameter was 5.99992 mm. Calculate the material's Poisson's Ratio, v. C) Calculate the material's Modulus of Rigidity, G.
