I need discussion and conclusion(seperatly) for “forces on plane surfaces:centre of pressure” lab expirement

you can clearly see above tha data we got from expirement

Answer 1

From this experiment it can be concluded that the hydrostatic pressure acting at the center of pressure counteracts the weight in the mass pan and that the two are directly related. Either the mass or the height of the water could be forced to be the independent variable. Since it was chosen that the mass would be independent, the level of the water had to compensate for the added weight in the mass pan. As the weight grew larger, the moment about the pivot, even though the moment arm remained the same. increased. This increase demanded the level of the water to be decreased in order to create a longer moment arm for the hydrostatic pressure of the water to counteract the force of the weight. By dropping the water level, it is possible to lower the center of pressure on the face of the torrid and create a larger moment to negate the added mass not only did the hydrostatic pressure act on the flat plane of the torroid, but also on the circular side of the toroid, however, it did not incur more of a moment in the arm Forces acting on a curved surface can be broken down into a horizontal and vertical force.These two forces Counteract each other in the moment equation. One the horizontal force, aides the mass pan, but the other, the vertical force, contributes to the pressure on the flat surface, thus negating each other.The fluid pressure was hydrostatic once the arm was horizontal. The water level needed to be lowered, just like in theory, in order to counteract the increased weight in mass pan.
