Best Answer

The center of gravity of an irregular shape can be measured, for example by hanging the object from two different points (points of the object), then watching where the lines (from the point where it is hung up downwards) intersect.

If you know details about the shape, the center of gravity can also be calculated by integration. Basically this means dividing (through calculation) the shape into small pieces, and adding up the results.

Each body has its own centre of gravity. The centre of gravity of two regular shapes - an equilateral triangle and a square will be different so why should the cog of a regular and an irregular shape not be different?

Irregular shapes are all around. Most shapes are irregular.

Bodies that are small and light (examples: moons of Mars) have low gravity and tend to have irregular shapes. Above a certain size, however, gravity is strong enough to overcome the strength of rock, forcing the body into a spherical geometry that minimizes surface area-to-volume ratio.

Irregular 3-dimensional shapes.

Regular shapes are both equilateral and equiangular. Irregular shapes may or may not be equilateral and equiangular.

For an object with symmetry around an axis, the center of gravity is at its center. For more complicated shapes, integration has to be used: basically, you imagine the object divided into small pieces, and take a kind of average. For many standard shapes, assuming uniform distribution of mass, this calculation has already been done and can be looked up (perhaps you may have to search for "center of mass" instead of "center of gravity"). For more irregular objects, if you know some rule (function) that describes its shape, you can do the integration yourself, if you know some calculus.For an object with symmetry around an axis, the center of gravity is at its center.

That "point" in a body where the entire weight of the body can be represented to be present. Extend your knowledge by exploring where the center of gravity would be for metal shapes formed in the shapes of circular, square, rectanglar, hexagonal rings with metal rods. Where would the center of gravity be, on the ring or outside the ring?

How the center of irregular shapes I am unaware of, but for triangles, where any one side is flat on altitude 0, the altitude of the center is 2 x Area divided by Perimeter That formula is used for getting the in-radius of a circle. The center of the circle of best fit is the center of the triangle.

Irregular galaxies have no discernible shape.

Regular shapes are both equilateral and equiangular. Irregular shapes may or may not be equilateral and equiangular.

No. As a simple example consider a donut shape! The center of gravity lies in the middle where the hole is.
