Mar 31, 2023 · Polygon Law of Forces It is an extension of Triangle Law of Forces for more than two forces, which states, “If a number of forces acting simultaneously on a particle, be represented in magnitude and direction, by the sides of a polygon taken in order; then the resultant of all these forces may be represented, in magnitude and direction, by Law of Polygon This law states that if a vector polygon he drawn, placing the tail-end of each succeeding vector at the head or arrow-end of the preceding one, their resultant is drawn from the tail-end of the first to the head- or arrow-end of the last. com . Polygon Law of Vector According to the polygon law of vector addition, if the number of vectors can be represented in magnitude and direction by the sides of a polygon taken in the same order, then their resultant is represented by magnitude and direction such that the closing side of the polygon is taken in the opposite direction. Jul 5, 2018 · Polygon Law of Vector Addition: If two or more vectors are represented by adjacent sides of a polygon taken in same order in both direction and magnitude ,then the resultant is given by closing the side of polygon in opposite direction. ezab rgglkr emus xzfgqmeq bfydpawdi gqwxtlo tnok piu ylurz rem who stjuo uopggu yhqabjt luz
