IIT Kharagpur · Answer

If a structure is acted upon by two force system Pa and Pb, in equilibrium separately, the external virtual work done by a system of forces Pb during the deformations caused by another system of forces Pa is equal to the external virtual work done by the Pa system during the deformation caused by the Pb system.
