METHODS OF FINDING RESULTANT

There are two methods for finding resultant

                                                (1)    Analytical Method

                                                (2)    Graphical Method

Analytical method = (a) Parallelogram Law.

                                    (b) Method of Resolution.

Graphical Method = (a) Triangle Law.

                                    (b) Polygon Law.

NON COPLANNAR NON CONCURRENT FORCE SYSTEM

       The forces which do not meet a point and their lines of action do not lie on the same plane , are called non coplanar non con current force system.

 F1, F2, F3 are three non-coplannar non-concurrent force system.

NON COPLANNAR CONCURRENT FORCE SYSTEM

The forces which meet at a point but their lines of action lies on different planes , are known as non coplanar concurrent force system.

F1, F2, F3 are three non coplanar concurrent.

NON COPLANNAR FORCE SYSTEM

                         The forces whose lines of action lies on different planes, called non-coplannar force system

F1, F2, F3 are three coplanar concurrent forces.
