QuoteI am a final year mechanical engineering student at Plymouth University and am writing my dissertation on the exploration of new improvements for the Columbian available at the university, without changing the fundamental working principle, i.e it is still to be hand operated.I have been unlucky in specifically identifying the exact material used, aside from being cast iron. I have used a spectrometer to work out the elements used in the composition of the cast iron, however, it does not show the amount of carbon content, therefore, I am a little stuck and would very much appreciate it if you could provide me with any help. I have assumed it to be gray cast iron as it is used for large mass structures, but i would like the exact or material properties from the 19th century in order to complete the evaluation and the calculations.Thank you very much
