In the same manner, we may find the pointof application G, of the resultant of gt+g2 acting at G, andg3 acting at g3, and so on; the last point so determined willbe the center of gravity G of… … plane will bisect all lines in the pyramid parallel to BC, andwill therefore divide it symmetrically. Bisect AC in F, andthe plane through F and the edge BD will also divide the pyr-amid symmetrically; and since the center of gravity of thepyramid will be in both these planes, it must be in their…
