Cg of a semicircle
The following is a list of centroids of various two-dimensional and three-dimensional objects. The centroid of an object in -dimensional space is the intersection of all hyperplanes that divide into two parts of equal moment about the hyperplane. Informally, it is the "average" of all points of . For an object of uniform composition, the centroid of a body is also its center of mass. In the case of two-dimensional objects shown below, the hyperplanes are simply lines. WebJul 27, 2024 · For a triangle of height h, the cg is at h/3, and for a semi-circle of radius r, the cg is at (4*r/ (3*pi)) where pi is ratio of the circumference of the circle to the diameter. …
