(a) In a heat exchanger, heat is added at constant pressure, therefore, use the formula for heat…

I have been working on this Solid Mech problem for a while and have gottem nowhere we are supposed to be finding the modulus of elasticity for a set of data (attached). I have made an excel sheet from this to finda stress strain graph. I understand how the modulus of elasticity is (E = (delta stress)/(delta strain)) but I cannot find the propotional limit that I need to find delta stress and delta strain
