yramid whose baseis any polygon. In the pyramid A BCDEF find G, the center of gravity ofthe polygonal base (Ex. 4),and join AG. Since AGpasses through the centerof gravity of the base, itwill pass through the cen-ter of gravity of every sec-tion parallel to the base,and the center of gravityof the… … 52 STATICS. sides. The centers of gravity of these pyramids will be atone fourth the distances, respectively, from the centers of grav-ity of their triangular bases to the common vertex A. Thesedistances being thus divided proportionally, the points of di-vision will all lie in the same plane…
