a) Plot the curve for force vs displacement.... for both the wet and the dry specimens (2 marks) b) Convert the data from the excel file to true stress vs true strain by completing the table below for only dry specimen and then plot the true stress vs true strain curve (4 mark) NB: The first 5 data points are presented below. You must complete the table for the whole data on the excel file and plot it. The curve should be included in the report but not the excel file.
