Given steps in procedure to find the center of gravity of the quadrilateral ABCD. Arrange the steps.i. Draw lines joining G1 with G2 and G3 with G4.ii. In given quadrilateral draw diagonal BD and locate centers of gravity G1, G2 of triangles BCD and ABD.iii. The point of intersection of lines G1G2 and G3G4 gives the center of gravity of the quadrilateral ABCD.iv. Similarly draw the diagonal AC and determine the centers of gravity G3, G4 of triangles ABC and ADC.

The center of gravity (COG) is the point in an object where the weight is distributed equally in all directions. It is also the point where the mass of the body is concentrated.  The center of gravity is dependent on the gravitational field. For example, the center of gravity and center of mass of an object are at the same point in a uniform gravitational field.  The center of gravity can be calculated by dividing the sum of an object's moments by the object's total weight. A moment is the product of the weight and its location, measured from a set point called the origin.  The center of... Show more

The center of gravity (COG) is the point in an object where the weight is distributed equally in all directions. It is also the point where the mass of the body is concentrated. 

The center of gravity is dependent on the gravitational field. For example, the center of gravity and center of mass of an object are at the same point in a uniform gravitational field. 
The center of gravity can be calculated by dividing the sum of an object's moments by the object's total weight. A moment is the product of the weight and its location, measured from a set point called the origin. 
The center of gravity of an object is directly beneath the point from which the object is suspended. For example, if a plate is suspended from point A, the line AD is vertical. If the plate is suspended from point C, the line CE is vertical. The center of gravity is at the intersection of AD and CE. 
The lower an object's center of gravity is to the ground, the more stable the object is.
