... external force and reaction on that part of the truss; i.e., all forces acting on the free body must satisfy the three equations of equilibrium [Eq. (3.11)]. For three-dimensional structures, the equations ... For some structures, however, such changes in dimensions may not be negligible. In these cases, the equations of equilibrium should be defined according to the deformed geometry of the...
