Note: Links BC$,$ BD$,$ CH$,$ GM$,$ and GH have twice the cross$-$sectional area of the other rods. You may choose

any non$-$zero values for the truss characteristics $($i$.$e$.,$ lengths, cross$-$sectional areas, material, spring

stiffness constants, and force$-$controlled load F$).$

Show all steps leading to the solution $($as we learned in class$)$:

All coordinate systems $($local and global$)$ must be clearly drawn on the truss schematic

All labels $($e$,$ n$,$ DOF's, etc.$)$ must be shown on the truss schematic

The reduced stiffness matrix

The full stiffness matrix

Etc.
