Consider again the two-bar truss in the figure below, again subject to the concentrated load F. However,for this problem, the bars are not necessarily the same size A₁ ‡ A₂ and 0₁ ‡ 0₂. The dimension L is still constant. (a) Analyze the model and calculate the bar forces and stresses in terms of F, A₁, A₂, Theta1, and Theta2 . (b) Calculate horizontal and vertical displacements of the load point, ux and u, respectively (use virtual work). They should be in terms of F, A₁, A2, 01, 02, L, and E.
