The balance condition of a planar crossing force system is the closing of its force polygon. According to the condition, the two unknown forces on a panel joint can be obtained rapidly and accurately by means of the graphic method and the AUTOCAD drawing tool in a computer, and so can the internal force of every bar of truss.
