ABSTRACT
Graphical solutions to problems involving vector forces are sufficiently accurate for many engineering problems and are invaluable for estimating approximate solutions to more complicated force problems. The resolution of coplanar force systems was then looked at in some detail, with both concurrent and non-concurrent systems being considered, also the fact that when resolving non-concurrent force systems, the single resultant force is always accompanied by a turning moment. The concept of turning moments and equilibrium is central to an understanding of non-concurrent coplanar force systems and their resolution. The method of tabulating values to find total vertical and horizontal components of the forces and turning moments within the system was also explained. The vectors representing the forces are then given the corresponding lower case letters. Bow's notation is a convenient system of labelling the forces for ease of reference when there are three or more forces to be considered.
