$(2)$ Determine the Shear Force and Bending Moments in each member of the framed structure shown below. Use stiffness method for the computation. Take $I={450}^{***}{10}^{3}m{m}^4,A=0\mathrm{.}012m^2$ and $E=200$GPa for each member respectively. This problem is adapted from Problem $16\mathrm{.}2,$ Chapter $16$; Hibbeler, R$.$ C$.,$ & Tan, K$.-$H$.(2012).$ Structural analysis $(8$th ed$.$ in SI Units. ed$.).$ Singapore: Pearson Education.
