$(15$ points $\frac{w}{10}$ point bonus$)$ Calculate a force per $ft$ of the dam $($assume $w=1ft)$ for

the concrete gravity dam illustrated below and calculated its point of applications

measured from point A along the dam's wetted face. The bonus, find the resultant force

on the inclined surface of the dam and the $l_R$ from point $A.$

FBD $(3)$

Resultant Force $=F{x}_r=$

kips $(8)$

Center of pressure above point $A=y_r=$

$ft(4)$

Resultant Force $=F_r=$

kips $(5)$

Center of pressure above point $A=y_x=$

$ft(5)$
