Tag: Forces acting on a truss Equations of Equilibrium

When a body is in static equilibrium, no translation or rotation occurs in any direction (neglecting cases of constant velocity). Since there is no translation, the sum of the forces acting on the body must be zero. Since there is no rotation, the sum of the moments about any point must be zero. In a two-dimensional space, these conditions can be written: where
