A rectangular gate with a width of a = 2 m and a height of b = 6 m on the side of a tank is held in place by a force F. The water height h in the tank is 10 m. Water Hinge a) Calculate the resulting force on the gate. h Gate b) How deep below the water level lies the center of pressure? F b. X c) Calculate the torque the water causes in the hinge. d) Calculate the force F needed to keep the gate closed if the force is applied in a height of x = 2.5 m. Hint: The second moment of a rectangle with width a and height b is: Ice = jabu
