Engineering Mechanics categories of equilibrium in two dimensions

This document discusses four categories of equilibrium in two dimensions: 1) Collinear force systems have forces that are collinear and the free body diagram uses ΣFx=0. 2) Concurrent force systems have forces that meet at a point and the free body diagram uses ΣFx=0 and ΣFy=0. 3) Parallel force systems have parallel forces and the free body diagram uses ΣFx=0 and ΣMz=0. 4) General force systems have forces in any configuration and the free body diagram uses ΣFx=0, ΣFy=0, and ΣMz=0.
