Principle of virtual work and unit load methodMahdi Damghani
The document summarizes the principle of virtual work (PVW) which is a fundamental tool in analytical mechanics. It defines virtual work as the work done by a real force moving through an arbitrary virtual displacement. The PVW states that if a particle is in equilibrium, the total virtual work done by the applied forces equals zero. Examples are provided to demonstrate how PVW can be used to determine unknown internal forces and slopes by equating the virtual work of external and internal forces.
