Weapon Center of Mass Calculator

The Weapon Center of Mass (COM) software allows researchers to easily determine mass properties of a weapon system. The tool presents a photograph of the weapon and allows the user to place weight anywhere on the weapon by clicking on the screen. After the weight is placed, the software returns the mass properties of the weapon, including the effects of the added weight. It is based on fundamental equations found in physics and biomechanics, and can determine the effects of as many as four added weights. The added weight can be accoutrements (such as new sights), additional weapons (such as a grenade launcher), or any other object that is mounted to the weapon.
