% Z2, the coordi-nates of B, etc. Also let W denote theweight of the whole body, Q its centerof gravity, and x, y, z, the coordinatesof Q. Since W is the resultant of Wi,W2, W3, etc., the moment of W aboutany Hne equals the algebraic sum of the moments of Wi, W2, W3, etc., about the same line (Art.… … Fig. 156 Thus, taking Wx = Wixi + W2X2 + W3X3 + •> from which equation x can be determined. Similarly, by taking momentsabout the x-axis we can get y. To get z, we imagine the body turned until they-axis is vertical, — the coordinate axes are assumed fixed to the body, — andthen take moments…
