Problem $2$: A saturated clay specimen of height $20mm$ and water content of $30\%$ was tested in

a consolidation test. Loading and unloading of the specimen were carried out. The thickness, $h,$

of the sample at the end of each stress increment$/$decrement is given in the table below.

a$)$ Plot the $e-logP$ curve,

b$)$ Determine $C_c$ and $C_r.$
