Calculate trusses.

Method of Joints. The free-body diagram of any joint is a concurrent force system in which the summation of moment will be of no help. Recall that only two equilibrium equations can be written. ΣFx = 0 Σ F x = 0 and ΣFy = 0 Σ F y = 0. This means that to solve completely for the forces acting on a joint, we must select a joint with no more ... Summary.
