Project 5: Use element matrices potential energy formulations to solve the beam problem shown in Figure.5. Find nodal displacement values. Make sure to construct the grid information table and one-dimensional elements' line/mesh with appropriate labeling, numbering and displacement, loads nodal points. Steel: E = 20(105) N/cm A = 20 cm?
