Mostly it has to do with the stability of whatever they're designing.
if you have a large complex object, like a jar full of different size coins, but know its center of mass then you can make a simplification of the jar to a point of mass at the center of gravity. A point is much simpler to physics on than a whole jar of different coins. in this case it doesn't matter what the object is made of.
The center of gravity of the truck
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?
It is always different depending on the object. For example a female humans' center of gravity is in the hip. as a male humans' center of gravity is in the chest. But once you have found the center of gravity in an object the center of gravity should be the same in every object like it.
The centre of gravity is the point through which one's whole weight acts for any orientation of the object. Without it we will lose balance.
important points about center of gravity
The center of gravity is a point on the airplane that the airplane would balance while sitting on the ground. The center of gravity or also called "the CG" is important in trimming the aircraft in flight as the weight has to balance out the forces on the wing. It is also important in aerodynamic maneuvers as the G-forces act through CG.

The center of gravity is an average of the location of the points of gravity. If you had a flying ring like a Frisbee but without the center, the center of the gravity would be in the hole.

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.

Since the atmosphere is more or less symmetric, its center of mass (center of gravity) gravity must be quite close to Earth's center.
