Q$\mathrm{.}2-$ The rectangular footing shown on the right is $2\mathrm{.}5m2m$ and carries a $30cm40cm$ column.

a$)$ Determine the maximum allowable load $Q$ the footing can carry

b$)$ Sketch the soil pressure for $Q$ in part $($a$).$

The soils have the following properties:

Soil $1$:

$c=10$kPa

$=15$

$=15k\frac{N}{m^3}$

Soil $2$:

$c=0$kPa

$=35$

$=19k\frac{N}{m^3}$
