1. The problem statement, all variables and given/known data Question simply asks to calculate the Youngs modulus. I've attached the question. 2. Relevant equations Youngs Modulus = (change in stress)/(change in strain) 3. The attempt at a solution okay, what i did was simply find the gradient between each of the points. However they were all different gradients, which means the graph isn't linear (i think). So then how do i solve it?
