These considerations show that the c.p. describes anellipse in the plane A ; and that the axes of this ellipseare those for which B vanishes; so… … Fig. 27. If the momental ellipse becomes a circle, as for instancein a square plate, or in a plate bounded by a regular poly-gon, the c.p. is always vertically below the CG. of the area,at a depth inversely proportional to the depth of the c.G. 68 EXAMPLES ON In fig. 27 the position of the CP. of…
