Extracted text: The gate shown in the figure is in raised position but initially is not filled with water. (a.) If the gate weighs 350 lb for each foot perpendicular to the drawing, what would be the vertical distance of the water level below the hinge at O to just begin the gate to swing up (rotate counterclockwise) and; (b.) if h = 1 ft, what must be the weight of the gate in order to maintain its vertical position (raised position). The centroid of the gate is shown, Woler 2 ft 1.5 ft
