Multiple Choice Question How is the total-body center of gravity (CG) determined by the segmental method? Multiple choice question. The total body mass is multiplied by the sum of each body segment's CG location. The subject is placed on a platform such that total torque is zero and the distance of the subject's CG plane to the platform is calculated. The subject is placed on a platform and the reaction force of the platform is measured. The products of each body segment's CG location and its mass are summed and subsequently divided by the sum of all segmental masses
