Chapter 3, Problem 3.7QPP

A vertical load of 300 kN is applied to a $1.5\text{m}\times 1.5\text{m}$ area at the ground surface that is level.

1. Compute the induced vertical stress, $\Delta {\sigma }_z,$ at a point 2.0 m below the corner of this square loaded area.
2. Compute the induced vertical stress,

$\Delta {\sigma }_z,$ at a point 2.0 m below the center of this square loaded area.
