Unformatted text preview: different number, choose the answer that's closest to the number you come up with. Note that the axes scales are given in ksi and %. T he strain scale is given in % on this curve so 5% on this curve is equivalent to 0.05. Answer Selected Answer: 3.7 x 10 Correct Answer: 3.7 x 10 Response Feedback: Correct The elastic modulus is given by the slope of the σ-ε curve under elastic conditions. Using any two points on the curve (I used 0 and 1% for strain and the corresponding points 0 and ~37 ksi for stress), we can determine the slope mathematically;...
