...proposition is the same as explained in ?4, page 1 6. 124. (3) — // any number of forces acting at a point can be represented in magnitude and direction by the sides of a polygon taken' in order, they will be in equilibrium. Thus, let A, B, C and D (Fig. 269) represent four forces applied at one... | |
