$($i$)$ Plot the effective stress with depth calculated for the soil profile ignoring the surcharge load.

$($ii$)$ What stress is produced at the bottom of the footing $($soil$/$concrete

interface$)$ when your load is being placed upon the footing? Please explain how this stress will change with depth $($e$.$g$.,$ will it increase$/$decrease$?$ Explain why$).$ Which soil layer is expected to have the highest settlement?

$($iii$)$ Calculate the total elastic settlement.

$($iii$)$ What would be the total settlement in case if the foundation was rigid?
