Question:

Consider a clamped uniaxial bar subjected to a tip load as shown in figure 8.9. Use three elements of equal length to determine the tip displacement as a function of time. Use the central difference method for time integration and the consistent mass matrix. The properties of the bar are: \(E=100 \mathrm{GPa}, L=1 \mathrm{~m}, A=10^{-5} \mathrm{~m}^{2}, ho=4000 \mathrm{~kg} / \mathrm{m}^{3}\). The tip force is given by: \(F(t)=2 F_{\text {max }} t / t_{\max }\) for \(0t_{\max } / 2\), where \(F_{\text {max }}=0.001 E A\) and \(t_{\max }=3 \mathrm{~ms}\). Calculate the tip displacement \(u(t)\) for \(0
