as (3 \/ 3 -f-2/v/ 2) lbs. along A H, and (3 — 2\/2) lbs. along A N. Now, since A H and A N are at right angles, the resultant ofthese force^ = \^(3 \/3-(-2-y/2)-|- (3 — 2 V^) lbs. Let three forces of 8 lbs., 5 lbs., and 6 lbs., act along A B, 100 iDYNAMICS. A C, and A D (Fig. D). Let the angle B A… … For the force of 8 lbs. acting along A B, substitute its re-solved parts, 4 lbs., along A C, and 4 v/3 lbs. along A H. For the force of 6 lbs. acting along A D, substitute itsresolved parts, 3 lbs., along AC, and 3 \/:) lbs. along A K.Hence the oiiginal 3 forces have the same effect as a force of(5…
