Higher Study | Engineering Mechanics | Impact and Virtual Work

If a system is in equilibrium and the position of the system depends upon many independent variables, the principle of virtual work states that the partial derivatives of its total potential energy with respect to each of the independent variable must be
Who founded the principle of virtual displacement?
Let the force is given by F and displacement is given by D. If the values of force and length are modified such that: F = 2F and D = 3D What would be the final value of energy in such a scenario?
