Given steps in procedure to find the center of gravity of the trapezium ABCD. Arrange the steps.i. Join E and F which intersects the line PQ at G. G is center of gravity.ii. Similarly produce CD to a point F so that FD=AB.iii. Draw a line joining the midpoints P and Q of the parallel sides AB and DC respectively.iv. Produce AB to a point E so that BE=DC.

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.
