Given the table below summarizing data from a series of consolidated undrained triaxial compression test on sand. This series of tests were conducted on four samples with different relative densities but at the same confining pressure of $50$ psi. The provided data include measured axial strain, deviatoric stress during axial loading, and excess pore pressure during axial loading. $($a$)$ Plot the deviatoric stress vs$.$ strain curves for each sample. Plot all on the same Figure; $($b$)$ Plot the pore pressure vs$.$ strain for each sample. Plot all on the same Figure; $($c$)$ Plot values of effective principal stress ratio $(\backslash$sigma $1/\backslash$sigma $3)$ vs$.$ axial strain. Plot all on the same Figure; $($d$)$ Draw the effective and total Mohr circles at failure, total stress circles on one graph and effective stress circles on another graph; $($e$)$ Plot the total and effective stress paths for all samples using MIT method. Plot stress paths for each sample on a separate figure. On this plot of stress paths for each sample, show the Kf and K$$f lines. $($did you observe any differences in theses effective stress paths?$).$
