SUMMARY
Virtual displacement is a key concept in the D'Alembert principle, which states that the virtual work done by the applied forces during a virtual displacement is equal to the virtual work done by the inertial forces. This principle is crucial for analyzing dynamic systems in classical mechanics. An example provided in the discussion illustrates how virtual displacement applies to a system of particles, emphasizing its role in deriving equations of motion.
