Question 5 An important problem in structural engineering is that of finding the forces in a staticaly determinate truss (see tgurel 1000N 90 This type of structure cen be described as a system of the of coupled linear algebraic equations derived from force balances. The sum node because the system is at rest. Therefore, for ode 1 For node 2 For node 3 where Fis is the external horlzontal force applied to node /(where a positive torce is ve tical force applied to node (where a positive force is upward Thus nti, problem the OO ON corresponds to F-1000 For this cese, all other Fy's and Pas's are zero own ward force on node 1 Express the given set of linear algebraic equations in matrix form (Round the final answers to six decimal places) Using Matlab, find the values of the unknowns
