The Principle of Virtual Work states that for a system in static equilibrium, the total virtual work done by all external forces acting on the system is zero for any virtual displacement. Mathematically, it is expressed as: δW = Σ Fᵢ · δrᵢ = 0 Where: Fᵢ is the i-th external force acting on the system. δrᵢ is the virtual displacement corresponding to the force Fᵢ. Σ denotes the summation over all external forces. This principle is fundamental in mechanics and is used to analyze the equilibrium of complex structures and mechanisms. Send me the next one 📸
