THEORY: Law of polygon of forces is used to determine the resultant of coplanar concurrent force system consisting of more than two forces. The law states â€œWhen more than two coplanar forces acting at a point are represented in magnitude and direction by the sides of a polygon taken in order, the closing side from the first to the last point of the polygon represents the resultant of the... The vector method provides an alternative method of calculating resultant force graphically, using polygon law of forces. The following points explain how the resultant in magnitude and the direction of a given number of forces may be calculated by the method of vectors with the help of the shown figures:

Definition: Triangle law of forces states that, If two forces acting at a point are represented in magnitude and direction by the two adjacent sides of a triangle taken in order, then the closing side of the triangle taken in the reversed order represents the resultant of the forces in magnitude and direction.... According to triangle law of forces, the resultant of P (= OA = BC) and Q (OB) is represented in magnitude and direction by OC which is taken in the reverse direction. Alternatively, to verify the triangle law of forces, the ratios , P/OA, Q/OB and R/O C, are calculated and are tabulated (Table).

for example : let us take two forces of magnitude 50N and 100N acting on a same geometric plane at an angle of 30 Í¦ and 60 Í¦ respectively. here, we can solve the following by triangle law of forces.... The forces forms a close polygon. 2.0 Theory When four forces or more acts in the same plane but in different directions on a stationary body, their lines of action meet at a point. Because of this the forces can be represented by a force diagram called the polygon of forces.

### The polygon of forces represent lot of forces leading in a simultaneously to one point so all this forces acting will make a figure or they are call Vector such as force, that has magnitude and direction and can be resolved into components that are odd functions of the coordinates.

- First Law of Equilibrium: A set of forces acting on a body will hold that body in equilibrium provided the vector sum of those forces adds to zero, i.e., provided the vectors representing the forces form a closed polygon when placed head to tail. Any two vectors (as shown in figure (a) below) may be added by the so-called "Parallelogram Law" to form one resultant vector (figure (b)). Thus, for
- Net force means the sum of all forces acting on the object. Using these two laws, we can say that Using these two laws, we can say that if the net force on an object is equal to zero, the object will not experience an acceleration.
- if several COPLANAR FORCES are acting at a point simultaneously such that each one of them can be represented in direction and magnitude by a side of a polygon, taken in order, then the resultant is given by the closing side in the reverse order.
- This is a quick way of finding out if the forces acting on an object are in equilibrium. This object experiences three forces. If it is in equilibrium then drawing accurate vector diagrams of each force one after the other will produce a closed triangle.
