$($a$).$ For deviator stresses $1,2,8($psi$),$ calculate Resilient modulus.

$($b$).$ For each deviator stress, plot confining pressure vs$.$ resilient modulus.

$($c$)$ In one figure, plot all three $(3)$ deviator stress vs$.$ resilient modulus

$($d$).$ Define proportionality between confinement, deviator stress, and resilient modulus.

Example

Resilient modulus tests were made on a fine$-$grained soil. The distance between the LVDT

clamps is $4in.).$ The average recoverable deformations measured by the two LVDTs

after $200$ repetitions of each deviator stress are shown in Table

Note. $1=6\mathrm{.}9$kPa,$1$ in$.=25\mathrm{.}4mm.$
