# A 5 m wide rectangular gate weights 280 kg. The gate is hinged at point B and leans against the floor at point A marking an angle of 40° with the horizontal as shown. The gate is to be opened from its lower edge by applying a normal force F at its center. Determine the minimum force F required to open the watergate For water take p=1000 kg/m3 and for the rectangular gate 1 = 1/12bh3.
