The gate shown in the figure is hinged at A and rests on a smooth floor at B. The gate is a square in shape with 3m x 3m in
dimension, while it is submerged in oil (SG = 0.82) as shown. The air above the oil surface is under a pressure of 7KP.. If the gate
weighs 5 KN, determine the vertical force "T" required to open the gate. (Notes: Hydrostatic force "F" is always perpendicular to the
plane surface. Also, the h is the pressure head located at the center of gravity of the object, which means, what will be the height of
the oil if I am going to convert the pressure at the top into oil)
