Question $4$: Moment on panel$($s$))$

A tank of water has a panel installed in the $x-z$ plane, shown as a shaded region in the figure below. Heights $h_1=8m$ and $h_2=12$ m $.$ Widths $b=36m$ and $w=28m$ and $L=7\mathrm{.}5m.$ Assume that the water is constant$-$density non$-$moving water with density $=1000k\frac{g}{m^3}.$ Calculate the $x-$component of the moment on the panel due to the pressure of water in the tank, relative to a pivot at location $(2).$ Give your answer in meganewtons times meters.

number rtol $=0\mathrm{.}02,$ atol $=1e-08$
