sf the depth of the rectangle. 84. Centre of Pressure on an Immersed Triangle. —Let the apex be at the surfaceand the base horizontal. Dividethe triangle (Fig. 52) into a largenumber of sections n by equidistant lines parallel to the surface.Then the areas of these sectionswill be proportional to… … Fig. 52. Draw a line from 0 to the middle point of the base.It will bisect all the small areas, and will therefore passthrough the centre of pressure of each one of them. Thecentre of pressure on the triangle therefore lies on thisline. Let it be at 6r, at a distance X from 0. Then theproducts px…
