magnitude. 10. A weight of 10 lbs. is supported by two forces, one of whichis horizontal and the other inclined at 30° to the horizon. Find theforces. 11. Forces of 5 lbs., 6 lbs. and 7 lbs. acting at a point are in equi-librium, find the cosines of the angles between them. 74 THE ELEMENTS OF… … Let AB, BG, CD, DE, EA, be the sides of a pentagonrepresenting forces on a particle at 0. Join AG, AD. The resultant oi AB, BG is AG, see Art. 72, AG,GD\sAD, AD,DE is AE. Hence the resultant of all the forces is the resultant ofAE and EA, hence the resultant vanishes, or the forcesare in…
