Calculate Center of Gravity









Formula

The formula to calculate the Center of Gravity (G) is:

\[ G = \frac{I}{V_{o} \cdot (B + M)} \]

Definition

Centre of gravity of the object is the point through which gravitational force is acting. Moment of Inertia is the measure of the resistance of a body to angular acceleration about a given axis. Volume of Object is the volume occupied by a submerged or floating object in a fluid. Centre of Buoyancy is the center of the gravity of the volume of water which a body displaces. Metacenter is the theoretical point where a vertical line through the center of buoyancy and center of gravity intersects the new center of buoyancy when a body is tilted in water.

Example Calculation

Let's assume the following values:

Using the formula:

\[ G = \frac{1.125}{54 \cdot (-16 + 16.99206)} \approx 0.0210000739202602 \]

The Center of Gravity is approximately 0.0210000739202602.
