Figure (3.12) shows two flexible trusses *A* and *B*. Truss *A* is moving towards truss *B* which is fixed. The horizontal and vertical displacement are prescribed for nodes **1** and **3** in truss *A*. The dynamic and static coefficients of friction are assumed to be **0.5** between the two trusses. Analytical solution for the problem can be readily found. The results precisely agrees with the analytical solution. Figures (3.13) and (3.14) show the displacements of nodes **1**, **2** and **6**. Figure (3.15) shows the contact forces at node **2**.
