The water storage tank has a round opening 0.5 meters in diameter, which is covered by a round plate that prevents the water from escaping. The brace is anchored to the container by means of four screws that are at equal intervals from each other on a circle with a diameter of 0.64 meters, as shown in Figure 3. Given that the center of the opening is located at a depth of 1.4 meters from the water, as shown in Figure.3 The weight per unit volume of water is given and equal to y. Note that the water pressure only acts on a part of the brace which covers the opening A. The equivalent force and the position of its action on the window (center of pressure) must be determined. B. Draw (free body diagram) for the plate. C. The force must be found in each of the screws, as a result of the action of the water pressure

Follow-up Question

hii, thank you for you answer, why cant i use this simple formula that i added in order to calculate the center of pressure , and Ic would be just (pi*r^4)/4 ? r=0.25

 

thank you
