the centre of gravity of the foriner must lie in the same•mvtival as that of the two triangles combined. In other words,if the area of the curvilinear figure, 7^7iHil/6^-i^^, with FG ^sbase, be considered as a weight R acting through its centre ofgravity, then the areas of the two triangles must… … V- 1 Fig. 127, EQUILIBKIUM POLYGON THROUGH THREE POINTS. 117 the verticals through F and G. Adopt, therefore, the followingconstruction ; By dividing into vertical strips find the area of the curvi-linear figure with base FG, Draw the pier verticals at the one-third points. Find the vertical…
