Assignment $2-$ Analysis using Matrix Flexibility Method

Q$1.$ Show that the truss shown in Figure $1$ is statically indeterminate to the second degree. By choosing the axial force in bar $c$ and $d$ as redundant, analyse the truss to determine the bar forces and the deflection components corresponding to the applied loads. Assume $A=50c{m}^2$ and $E=20000k\frac{N}{c}{m}^2$Q$2.$ Analyse the truss using flexibility method shown in Figure $2$ to determine the reactions and the internal forces in all truss members. Assume support A and $B$ as pinned and $AE$ is constant.
