ights to,, w2, wz, &c, act at their respectivecenters of gravity, verticallydownward, and therefore con-stitute a system of parallel for-ces. wx and w2 have a result-ant =w1+iv2 acting at somepoint a, such that iv1.Aa—iv2.Ba. The distance AB beinggiven, the distanceA a is de-termined by taking… … W3 CENTER OF GRAVITY. 47 First determining aC from the triangle aCB, in which BCBa, and the angle aBC are supposed to be known, we can de-termine the distance ab by the proportion iv, +w„ +U3, : w~=Ca : ab=Ca. ; • . 1233 wl-\-w2+w3 By continuing the same process, we should determine thepoint at…
