Question $2$

Develop the global stiffness matrix and element forces for the beam shown in Figure $2.$ The beam is in rectangle cross$-$section in $(0\mathrm{.}3$x$0\mathrm{.}5$m$)$ of width and length. Determine the nodal displacements and rotations at the two point supports. The beam is made up of Aluminum $6061-$T$6.$ Use manual calculation AND FEA simulation to evaluate the stress distribution and the displacement at each node and compare the results.
