The structure shown in Figure 2 consists of two cantilever beams with stiffness of EI = 20, 000, 000 kN-mm² connected together by two pin-ended rigid struts (i.e., struts can only carry compression or tension). A. Without making any calculations, sketch (using your basic statics and intuition) the approx- imate deflected shape, shear diagram, and moment diagram for the structure. B. Calculate the degree of static and kinematic indeterminacy of the structure (i.e., show how many internal forces or displacement are needed to characterize the loaded state). C. Solve for the reactions, internal forces in the rigid struts, and deflection under the load P using the force (flexibility) method of analysis. For this problem, you may use tabulated values of standard beam deflection formulae to simplify your calculations. D. Neatly draw the shear and moment diagrams for the structure indicating key points.
