Under a strip loaded area, applied at the ground surface, having a width B and carrying a uniform

pressure of $q,$ plot the vertical stress increase, ${}_v,$ contours $($as in CE$366$ Lecture Notes Figure $1\mathrm{.}4$

$($a$),$ and also show $0\mathrm{.}1$q pressure contour$)$ using Excel, Excel VBA, MATLAB, Python etc.

Hint: Vertical stress increase contour plot is symmetrical around the centerline of the loaded area. You

can draw the half of the contours and, then, mirror your sketch with respect to center line.

Hint: Vertical stress increase $({}_v)$ due to a uniform pressure of $q$ on a strip area of width $B$ can be

expressed as $($Equation $1\mathrm{.}10$ of CE$366$ Lecture Notes$)$:

${}_v=\frac{q}{}[+sincos(+2)]$ where $$ and $$ are $in$ radians
