Centre of gravity of body or system of particles rigidly connected together is that point through which the line of action of the weight of the body always passes from all position of the body. Centroid or centre of area is defined as the point at which the total area of a plane figure such as rectangle, square,traingle, quadrilateral,circle etc.,is assumed to be concentrated.The centroid and centre of gravity are at the same point when the bodies have area only and not weight.
