Q$1)$

$10-6.$ Calculate the stress distribution with depth at a point $3\mathrm{.}5m$ from the corner $($along the longest side$)$ of a rectangularly loaded area $15$ by $35m$ with a uniform load of $75$kPa.

$+{?}^{(15,38\mathrm{.}5)}$

$q_0=75$kPa and $z$ varies

Determine the stress increase using Fig. $10\mathrm{.}4($or Eq$.10\mathrm{.}6)$ for the vertical stress under the corner of a uniformly loaded rectangular area. Use superposition as necessary. $($Influence values presented below were determined using the Boussinesq solution as given by Eq$.10\mathrm{.}6.)$
