Problem 5.15 Hinged flat plate swung against wall A flat plate is hinged at one side to s smooth floor, as shown, and held at a small angle o ( o << 1) relative to the floor. The entire system is submerged in a liquid of constant density . At t = 0, a vertical force is applied and adjusted continually so that the rate of decrease of the plate angle
