3. A series of four (4) Carnot engine are arrange in the manner that the proceeding engine receives the heat rejected by the former engine as a heat input in the cycle. If all the temperature limits of the engine ranges from 30°C and 300°C and the heat input in the first engine is 300kJ/kg of working substance, determine the following (a) net total work that can be given off by the engines (kJ/kg), (b) Net work output of the 4th engine (kJ/kg), and (c) Heat rejected by the 4th engine (kJ/kg)

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
