Resultant Force :
It is a single force which produces the same effect as produced by all the given forces actung on a body. The resultant force may be determined by the following three laws of forces
Parallelogram law of forces:
It states that if two forces, acting simultaneously on a particle be represented in magnitude and direction by the two adjacent sides of a parallelogram, then the result may be represented in magnitude an direction by the diagonal of a parallelogram which pass through their points of intersection
Triangle law of forces:
It states that if two forces, acting simultaneously on a particle,be representing magnitude and direction by the two sides of a triangle taken in order, then their resultant may be represented in magnitude and direction by the third side of the triangle taken opposite order
Polygon law of forces:
It states that if a number of forces, acting simultaneously on a particle,be represented in magnitude and direction by sides of a polygon taken in order, then their resultant is represented in magnitude and direction by the closing side of the polygon taken in opposite order.
