Resultant of force system - mechanics, Mechanical Engineering

Resultant of force system:

Resultant is single force that produces the same effect as produced by the number of forces jointly in the system. In equilibrium magnitude of resultant is always equal to zero.

There are many different ways to find out the resultant of the force system. But the first thing which has to be seen is that how many forces is acting on body,

1.  If only one force act on body then that force is resultant.

2.  If two forces are acting on rigid body then there are two methods for finding out the resultant, that is 'Parallelogram law' (that is Analytical method) and 'triangle law' (that is Graphical method).

3.  If more than two forces are acting on a body then the resultant is finding out by 'method of resolution' (which is Analytical method) and 'Polygon law' (which is Graphical method).

So we can say that there are basically two type of method for finding the resultant which are stated below.

1. Analytical Method.

2. Graphical Method

Finally; the resultant force, of given system of forces, can be found out analytically by following methods:

(a) Parallelogram law of forces

(b) Method of Resolution.
