## principal axes

the axes of a body or object around which the moment of inertia (resistance to rotation) is greatest, least and intermediate. With reference to the human body in the standing position, the axis for maximum moment of inertia is the sagittal axis (front to back), for minimum is the vertical axis and intermediate is the frontal ( syn transverse ) axis (side to side), all axes passing through the midpoint of the body (where the frontal, sagittal and transverse planes intersect).
