Question

application of polygon law examples

Answer 1

Answer:

a broken line that is constructed to determine the resultant vector (geometric sum) of a given system of forces. In order to construct a force polygon for the system of forees F1, F2, … , Fn; (Figure 1, a), we successivel plot the following vectors in the chosen scale. The vector Polygon of Forces which represents the force F1, is plotted from an arbitrary point a; the vector Polygon of Forces which represents the force F2, is plotted from the head of the first vector. Continuing in this manner, we finally reach the vector Polygon of Forces this last vector, which represents the force Fn, (Figure 1,b), is plotted from the head m of the penulti-mate force.
