1. The problem statement, all variables and given/known dataEvaluate the net force on a 200 -m high dam with a 60 mwater depth. 2. Relevant equations P=F/A p(hydrostatic pressure)=rhogh+patm 3. The attempt at a solution The atmospheric pressure acts on both the dam and the water, so it cancels out of the equation. g=9.8m/s^2, rho=1,000 kg/m^3,d=60m F=P*A => dF= integral(rhogh)*(wdy) = rho*g*d*w (y) Integrated from y=0 to y=200 =(1,000 kg/m^3 *9.8m/s^2*60m*200 w )-0 But, I was not given width, so how else can I find the net force acting on the dam. All I know is that it remains constant.
