Unformatted text preview: that s fs f f ff U K P U K − = . Here, f P is a vector which contains the applied forces, and f U contains corresponding displacements (viz. the "free degrees of freedom"), while s U contains specified/prescribed displacements and s P contains associated forces (viz. the reactions). For the problem under consideration, state explicitly all of the vectors and sub-matrices which appear in these relations. (f) Solve f U and s P . (g) Show that (with the reactions s P which you determined above) the structure is in fact in equilibrium. (h) Determine the internal force acting in each bar...
