A solid cylinder of width (into the page) B = 2.0 m and radius R = 0.8 m is hinged at point A creating an automatic gate, as shown in the figure below. When the water level reaches how = 4.4 m, the gate opens automatically by turning about the hinge at point A. h_w X A R Determine the magnitude of the hydrostatic force acting on the cylinder when the gate opens = kN.
