  2. Forces on Gates p0 hc yc p0 Balancing force on Gate is --hc depth to centroid Point of application—slant distance to free-surface yc Slant distance to centroid Dimension into page If plate is rectangle, Area = length x breath, A = l x b. I = (b x l3) /12 Fig A1 If plate is ellipse, Area = pa x b, I = (pb x a3) /4
