helpb$)$ Figure $2($b$)$ shows a strip footing of breath, $B=2m$ resting on the clayey soils. The soils parameters and loading parameters are given in the figure. Establish the maximum permissible load, $V$ with compliance of the bearing resistance limit state using conventional approach and EC$7$ Design Approach $1.$ Compare and comments on both results.

$c_u=70k\frac{N}{m^2}$

$=20k\frac{N}{m^3}$

$q=10k\frac{N}{m^2}$

$W=40k\frac{N}{m}$
