That must be obtained through integration, meaning, you divide the solid into many small pieces.
That all depends on the shape of the object and how its mass is distributed. The center of gravity of a solid sphere is at the center of the solid sphere. The center of gravity of a solid cube is at the center of the solid cube. The Earth's center of gravity is at the center of the Earth, and there's certainly plenty of mass there. But the center of gravity of a ring is at the center of the ring ... an open space where the finger goes.
No, the center of gravity of a solid body may not always lie within the body. It depends on the distribution of mass within the body. If the mass is distributed symmetrically, then the center of gravity will be located within the body. However, if the mass distribution is asymmetrical, the center of gravity may lie outside of the body.
The center of gravity of irregular objects can be measured by hanging the object freely and observing where it balances perfectly. Another method is to calculate the average position of the weight distribution in each dimension. Computer software can also be used to model the object and determine its center of gravity.
The center of gravity of an irregular object can be determined by finding the point where the object would balance perfectly in any orientation. This can be done by supporting the object at different points and adjusting until it is balanced. The center of gravity is typically the point where all these balancing points intersect.
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?
centroid
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.
The effect of gravity inside a solid sphere is that it pulls objects towards the center of the sphere, with the force of gravity decreasing as you move towards the surface. This is because the mass of the sphere is concentrated at the center, creating a gravitational pull towards that point.
The factors affecting the center of gravity of an object include its shape, mass distribution, and orientation relative to a reference point. Objects with irregular shapes or uneven mass distribution tend to have a less predictable center of gravity. Changes in the object's position or orientation can also affect the location of its center of gravity.
Sorry but you need to be a little more clear next time
