Each bar has a cross-sectional area of A and a Young’s modulus of E. Before it is loaded, the bars fit together without interference (neatly, with nothing having to be forced into place). What are the forces in the bars and what is the displacement of point F when the load P is applied as shown? Problem 6: (15 points) A 45 degree truss is built from bars pinned at A, B, C, and D (no pin where the

Before it is loaded, the bars fit together without interference (neatly, with nothing having to be forced into place). The truss is then loaded as shown in the diagram at right.

Problem 7: (15 points) The rigid bar AC is pinned to the wall at point A and is also pinned to the deformable bars shown below. The deformable bars each have a cross sectional area of A and a Young’s modulus of E. Before the structure is loaded, the parts fit together without interference (neatly, with nothing having to be forced into place). What is the displacement of point B when the load is applied? What is the force in bar CE when the load is applied? L W D L E A B C L L...
