A plug in the bottom of a pressurized tank is conical in shape, as shown in Fig. P2.65. The air pressure is 40 kPa and the liquid in the tank has a specific weight of 27 kN/m³. Determine the magnitude, direction and line of action of the force exerted on the curved surface of the cone within the tank due to the 40-kPa pressure and the liquid.
