In the figure, aluminum [E = 72 GPa] links (1) and(2) support rigid beam ABC. Link (1) has a cross-sectional area of 260 mm² and link (2) has a cross-sectional area of 500 mm². For an applied load of P= 32 kN, determine the rigid beam deflection vg atpoint B. Assume a = 1610 mm, b = 770 mm, L₁=2540 mm, and L₂ = 4180 mm.
