Draw the free-body diagrams of member ACB and member CD. Considering the system in static equilibrium, find the force P if the compressive force in member CD is 2 kN. (Bar ACB is horizontal, 3 m long and pinned to a wall at A; C is its midpoint; link CD is pinned at C and to the wall at D, 1.5 m directly below A; P acts vertically at end B.)
