A device consists of a horizontal beam ABC supported by two vertical bars BD and CE. Bar CE is pinned at both ends but bar BD is fixed to the foundation at its lower end. The distance from A to B is 600 mm and from B to C is 350 mm. Bars BD and CE have lengths of 350 mm and 450 mm, respectively, and their cross-sectional area is 720 mm². The bars are made of steel having a modulus of elasticity E = 200 GPa. If load P is 20 kN, calculate the displacement at point A.
