CENTER OF GRAVITY
The Center of Gravity (CG) of an object such as a car, is the point at which the object
will balance when placed on a pivot point. The following diagram demonstrates two
Center of Gravity scenarios where the weight is represented by the force applied by two
tires of the car.
In the first example, the weight applied to each tire is the same. The CG is exactly in the
middle of the scale. The second example depicts one tire that is 3X heavier than the
other tire. In Example 2, the CG is closer to the heavier tire.
CENTER OF GRAVITY EXAMPLES
Example 1 Example 2
A car has three axis; 1) Front to Back, 2) Left to Right, 3) Top to Bottom. The center of
gravity of the first two axis can be determined directly by the weight of each wheel. The
Top to Bottom or Vertical axis, requires that one end of the car be raised up. The Top to
Bottom or Vertical axis CG is addressed in the Vertical CG section.
