I read about Saint-Venant principle which is about the effect of replacing forces by equivalent forces system that effect on the same small region of a rigid body, all examples I come across are on replacing axial force acting on a column by equivalent distributed force,so my question is about replacing distributed force on small region by point force in thin beams, is that considered an application of Saint-Venant principle?
