A 4-m-high, 3-m-wide rectangular plate blocks the end of a 3-m-deep freshwater channel, as shown in the figure. The plate is hinged about a horizontal axis along its upper edge through a point A and is restrained from opening by a fixed ridge at point B. Determine the force exerted on the plate by the ridge. In the figure, the total height (s+ h) is 4 m where s is 1 m. h The force exerted on the plate by the ridge is KN.
