What are the formulas for finding geometric center of gravity, centroid and centroid?
The calculation formula is ∫∫ dxdy = abscissa area of gravity center × d.

The formula for calculating the center of mass is ∫∫ dxdy = the area of the abscissa x d of the center of gravity ∫∫Dydxdy= the area of the ordinate x d of the center of gravity. Centroid is the geometric center of cross-section graphics, which is aimed at physical objects, while centroid is aimed at abstract geometry. For real objects with uniform density, the centroid and centroid coincide.

The geometric center of a convex object is always in it. The geometric center of a non-convex object may be on the outside, such as the geometric center of a ring or bowl is not on the inside.

The center of gravity of a triangle is connected with three vertices, and the areas of the six triangles are equal, and the distance from the vertices to the center of gravity is the center line.

Center of gravity, center of gravity, center of gravity, center of gravity, center of gravity, center of gravity, nine o'clock. The center of gravity, the heart, the nagel point and four points similar to the center of gravity. The center of gravity of the triangle is also the center of gravity of the midpoint triangle. The center of mass is the geometric center of a triangle, which is usually called the center of gravity. The intersection of the three midlines of a triangle (the connecting line between the vertex and the midpoint of the opposite side) is the center of gravity.
