The cg of any freely suspended object lies directly

This preview shows page 15 - 17 out of 17 pages.

The CG of any freely suspended object lies directly beneath (or at) the point of hanging . The CG may be a point where no mass actually exists. For example, the center of mass of a ring or a hollow sphere is at the geometrical center where no matter exists. Similarly, the center of mass of a boomerang is outside the physical structure, not within the material making up the boomerang.
