Question:

Use the FEM to determine the displacements and forces in the space truss, shown in figure 1.21. The coordinates of the nodes in meter units are given in table 1.3. Assume Young's modulus \(E=70 \mathrm{GPa}\) and area of cross section \(A=1 \mathrm{~cm}^{2}\). The magnitude of the downward force (negative \(z\) direction) at node 4 is equal to \(10,000 \mathrm{~N}\).
