Question:medium
The virtual work done by external active forces on an ideal mechanical system in equilibrium is ______ for any and all virtual displacements consistent with the constraints.
The virtual work done by external active forces on an ideal mechanical system in equilibrium is ______ for any and all virtual displacements consistent with the constraints.
Show Hint
The Principle of Virtual Work is extremely powerful because it allows us to solve complex equilibrium problems for multi-body mechanisms without calculating internal constraint forces.
