PROBLEM $2\mathrm{.}2$:

A circular footing $2\mathrm{.}5$ m in diameter is to be constructed $1\mathrm{.}8$ m below the ground surface. Assume that

$=18\mathrm{.}45k\frac{N}{m^3},{}_{\text{s}\text{a}\text{t}}=19\mathrm{.}24k\frac{N}{m^3},{}^{\text{'}}=28$ and $c^{\text{'}}=80k\frac{N}{m^2}.$ The water table is located

at a depth $1\mathrm{.}12$ m below the bottom of the footing. Assume general shear failure and use a factor of

safety of $3.$ Determine the gross allowable load the footing can carry using Meyerfof formula.
