A rectangular gate, shown in Fig. Q5b forms a wall of a tank which holds water to a depth of 2m. The gate is hinged at the base and is 3m wide. i) Calculate the pressure at the base of the tank and show the pressure variation with height. ii) Using integration, calculate the force P acting perpendicular to the gate, which is required to keep the gate held at angle of 40°.
