Use the technique virtual work to solve: A force of 800 N acts downward at A on the mechanism, which is pinned at B, has a roller at D, and is attached to a spring with a force constant of 6kNm. The spring is unstretched when =0. All members are joined by frictionless pins. Calculate at equilibrium.
