Explanation
D’Alembert’s principle is mainly used to convert dynamic problems into static ones by introducing inertial forces, simplifying the analysis of kinetics. It is not primarily intended for stress analysis in trusses, stability of floating bodies, structural safety design, or purely kinematic problem solving.
