A $192-$foot high tower is built on the soil profile shown in Fig. $1.$ The circular base has a

diameter of $64$ feet and rests at the depth of $10$ feet in the sandy silt. The weight of the tower is

$14,453$ tons $(1$ ton $=2000lbs).$ Assume a uniform contact pressure between the base of the

tower and the sandy silt.

Calculate the effective stress at each of these depths. Depths in feet: $(21\mathrm{.}5,51,75\mathrm{.}5,111\mathrm{.}5).$ Then,

calculate the applied stress from the tower load at the centerline of the footing and at the edge of the

footing for each depth. You should have $4$ effective stresses and $8$ applied stresses, one at the

centerline and one at the edge for each of the $4$ depths.
