Water stands at a depth h behind the vertical face of a dam. It exerts a resultant horizontal force on the dam tendibg to slide it along its foundation and a torque tending to overturn the dam about the point `O`. Find

(a) Horizontal force,(b) torque about O, (c ) the height at which the resultant force would have to act to produce the same torque,l=cross-sectional length and `rho=`density of water.
