A fixed beam as shown in figure, having concentrated load of 10 kN, 20 kN and 30 kN at point A, B and C respectively, produces a vertical deflection ΔA = 10 mm, ΔB = 20 mm and ΔC = 30 mm, respectively.
What is the deflection at A if the deflections under point B and C are 20 mm and 10 mm respectively, when loads of 40 kN and 20 kN are applied at A and B, respectively?
