3. For the two-bar structure shown below, determine the global stiffness matrix K and the force vector F. Then solve the resulting set of equations to determine the vector of nodal point displacements. Finally, use the element stiffness matrices to determine the element nodal forces for each element. F₂ = 4500 N 1 2 2 = -6000 N 3 Take L₁ = 0.75 m, L2 = 0.50 m, A₁ = 300 cm², A2 = 100 cm², E₁ = E2 = 80 GPa.
