Center of GravityThe center of gravity of an object is the pointat which all the weight of an object might beconsidered as acting for purposes of treatingforces and torques that affect the object.The single support force has line of action that passesthrough the c. g. in any orientation.
Examples of Center of GravityNote: C. of G. is not always inside material.
