Center of Gravity


What is the Center of Gravity?

The “Center of Gravity” (COG), or “Weight Center,” of an object is the point where the entire weight of the object is considered to be concentrated. This point is the theoretical location where a vertical line passing through it balances the total weight of the object. The center of gravity is important for understanding the balance and movement of an object. The lower the center of gravity of an object, the more stable it is. Similarly, if the center of gravity of an object is positioned forward or backward, it is more prone to tipping over.

For homogeneous and symmetric objects, the center of gravity coincides with the intersection point of the object’s symmetry axes. However, for irregular objects, the center of gravity varies depending on the shape and distribution of density.


Methods for Finding the Center of Gravity:

  • Balancing Method: The object is supported from two points, and when it comes to equilibrium, the midpoint between these two points provides the center of gravity.

  • Sectioning Method: The object is cut into parallel sections, and the center of gravity of each section is determined. These individual centers of gravity are then used to calculate the overall center of gravity of the object.

  • Integration Method: If the density distribution function of the object is known, the coordinates of the center of gravity can be calculated using integrals.
