註釋

A simple method is described for experimentally finding the principal moments of inertia and the directions of the principal axes for a rigid body with only one known plane of symmetry in mass distribution. The torsion pendulum method is used, although this method is generally applicable only when a principal axis of the body coincides with the gravity direction. A rapidly converging process is demonstrated for obtaining accurate data, without the above restriction which serves to locate the orientation of all principal axes. The technique was tested against known bodies, and then used to find the inertial properties of a typical sabot component for the XM 735 projectile.
