The truss ABC shown in the figure supports a horizontal load P₁ = 9 kN and a vertical
load P₂ = 18 kN. Both bars have cross-sectional area A = 1,290 mm² and are made of steel
with E= 210 GPa.
a) Determine the strain energy U₁ of the truss when the load P₁ acts alone (P₂ = 0).
b) Determine the strain energy U₂ when the load P2 acts alone (P₁ = 0).
c) Determine the strain energy U when both loads act simultaneously.
