Q$\mathrm{.}1.$

A sieve analysis of a soil sample was carried out in the laboratory and the results are given in th Table $2$ below. Also the natural water content, LL and PL are given in the Table $3.$

Answer the following according to your group $($see Table $1$ below

$($a$)$ Plot the grain size distribution

$($b$)$ Make a histogram plot $($frequency plot$)$ for only one soil as shown in the list below. Use suitable intervals.

$($c$)$ Find the percentage of gravel, sand and fines according to USCS.

$($d$)$ Find the percentage of gravel, sand and fines according to AASHTO. How this compares to $($c$)?$

$($e$)$ Calculate $C_u$ and $C_c($when applicable$)$

$($f$)$ What is the effective diameter?

$($g$)$ Determine the plasticity index $($PI$)$ and Liquidity index $($LI$)$ for each soil $($when applicable$)$ and comment on the state of the natural soils $($i$.$e$.,$ solid, liquid $...$etc.$).$

$($h$)$ Classify the soils according to the Unified Soil Classification System $($USCS$).$ Give the soil name and symbol.

$($i$)$ Classify the soils according to AASHTO classification system. Give the soil name and symbol. Determine the group index $($GI$)$ for each soil. Rate the soils from the best to worst for use as a pavement material.

$($j$)$ Comment on your results in $($a to h$).$

$($k$)$ If you have to select a soil for a roadway that requires good drainage qualities, what soil type $($s$)($from the $4$ soils you analyzed above$)$ would you select and why?

Question $1$: $(5$ Pts$)$

To damp oscillations, the pointer of galvanometer is fixed to circular disk which turns in a container of oil as shown in the given figure. What is the damping torque $($N$.$m$)$ for angular velocity $0\mathrm{.}3ra\frac{d}{s}$ and oil viscosity of $8{10}^{-3}Pa.$s $?$ Neglect edge effects.
