1. The problem statement, all variables and given/known data The figure shows the stress-strain curve for a material. The scale of the stress axis is set by s = 280, in units of 10^6 N/m2. What are (a) the Young's modulus and (b) the approximate yield strength for this material? 2. Relevant equations E=stress/strain 3. The attempt at a solution so i know that for part a i needa divide 280/.004 but im not sure what it means to use units of 10^6. also shouldnt part b be 280? the unit that is correct is N/m^2 (its an online grading program that told me this is correct) and i cannot answer a 10^6 or any 10^.... (the system wont read it) what am i not understanding?
