Consider the Fig. 9.3,
Let us consider the reactive forces are Ax, Ay and N on two rigid bodies. Both these bodies are considered to be in equilibrium so there will be no work.
If P and Q acts on the bodies to do virtual work, the internal forces will act as reactive forces to cancel the total work.
