Graphical solutions of Resolution:

This topic looks at deriving graphical solutions to problems involving the Addition of Vector Quantities.

Firstly, the quantities must be vector quantities.    Secondly, they must all be the same, i.e. all forces, or all velocities, etc. (they cannot be mixed-up).

Thirdly, a suitable scale representing the magnitude of the vector quantity should be selected.

Finally, before drawing a Polygon of vectors, a reference or datum direction should be defined.

To derive a solution (i.e. a resultant), proceed to draw the lines representing the vectors (be careful to draw all lines with reference to the direction datum).

The resultant is determined by measuring the magnitude and direction of the line drawn from the start point to the finish point.
Note that the order in which the individual vectors are drawn is not important.
