Is it necessary for the centre gravity to be situated inside the body of irregular shape?
No. As a simple example consider a donut shape! The center of gravity lies in the middle where the hole is.
What is the center of gravity for a lamina?
If the lamina is in two dimensions (i.e. not curled round into a third dimension) then the centre of gravity will be somewhere within the flat shape. The position of the centre of gravity will depend on the distribution of mass across the lamina. If the lamina is curled round into a third dimension then the centre of gravity will be somewhere within the volume enclosed, fully or partially, by the lamina; this may or may not be on the lamina.
What is center of gravity of a body?
The center of gravity is the theoretical point where all the body weight is concentrated or the theoretical point about which the body weight is evenly distributed. If a body is of uniform density and has a symmetrical shape the center of gravity is in the geometric center. If the object is not symmetrical and does not have uniform density, it is more difficult to describe the location of its center of gravity.
How does the centre of gravity change as the size of the object changes?
The location of an object's center of gravity depends on the object's shape, and on how its mass is distributed throughout its shape, but not on its size. The center of gravity of a homogeneous sphere is at the center of the sphere, no matter whether the sphere's radius is 1 millimeter or 1 light year.
Center of gravity of a flat plate?
C.G of a regular shaped plates of uniform thickness will be at its centre. But if it is irregular, it can be inside or outside the lamina as well. please give more details of shape and if it is solid and has uniform plane etc.
Why is the center of gravity different between regular and irregular shapes?
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?
Why does trhe center of gravity of regular shapes always be in the middle of the shape?
There may be a clue in the similarity of meaning between the words CENTRE and MIDDLE.
Does the centre of gravity change on moon?
As compared to Earth, you mean? If an object doesn't change its shape, the center of mass doesn't depend on gravity - and the center of gravity hardly does so.
Is it necessary for the centre gravity to be situated inside the body of irregular shape?
No. As a simple example consider a donut shape! The center of gravity lies in the middle where the hole is.
Does the centre of gravity always lie inside the body?
No. The classic counterexample is the torus (ring-shape); the center of gravity is in the geometric center of the ring, which is NOT part of the ring.
What is the center of gravity for a lamina?

Why a men bow himself while carrying heavy lod on his back?
Every object on the Earth is governed by a force called Gravity. But regardless to the shape of the object, every oject has a 'centre of Gravity'. To, attain the position of stability the centre of gravity and the centre of mass of that object should be on same vertical line (perpendicular to earth). So, when man lift the heavy weight it total mass increased and and the centre of mass deviates from the centre of gravity of that man (man+ weight), so to maintain the stability man bow down to bring back its centre of mass with its centre of gravity. and in this way he can walk/stand with the load, otherwise we will fall back with its load.

The location of an object's center of gravity depends on the object's shape, and on how its mass is distributed throughout its shape, but not on its size. The center of gravity of a homogeneous sphere is at the center of the sphere, no matter whether the sphere's radius is 1 millimeter or 1 light year.
What polygon is a regular star?
A 'concave decagon' is a ten-sided shape with every other corner pushed in towards the centre. It forms a regular five-pointed star.
When was SHAPE Technical Centre created?
SHAPE Technical Centre was created in 1955.
Is the centre of gravity the same for an object placed on the moon and the surface of the earth?
Yes. COG is determined by the object shape & density distribution, not by its location.
