The bar shown below has constant AE and is subjected to a longitudinal force per unit length given by q(x)= = 100x N/m L q(x) X Adopt E=200 GPa, L=10.0 m, A=5 cm². (a) Derive the exact solution for the axial displacement of the bar. (b) Using the FEM, compute nodal displacements using i) One element; ii) Two elements of equal length. (c) Plot the axial displacement (y-axis) versus the position along the bar (x-axis) using the solution computed in items (a), (b-i), and (b-ii). (Plot the three curves in the same figure.) (d) Write the observations about the FEM solutions plotted in item (c). TTT
