Cylindrical Soil Sample

a$)$ The cylindrical soil sample begins at stress state where ${}_v={}_h=60$kPa. Plot the point associated with the stress state on a p$-$q stress path. Then, the vertical stress is increased while the horizontal stress remains at $60$kPa. The soil reaches a failure state when $k=\frac{{}_h}{{}_v}=0\mathrm{.}25.$

Plot the point on the stress path where soil reaches failure, and connect the initial to failure points with a line representing the intermediate stress states. Identify the coordinates of the initial and failure states.
