A weight W= 120 kN is being supported by steel sections with force T, force F, andforce C. The coordinates of A, B, C, and D are given. Assume that E is the origin(0,0,0). Determine Forces T, F, and C. (Hint: Produce three equations fromequilibrium of force system)Note: The Forces T, F, and C must be computed accurately to design the proper sizes ofsteel sections in the subject “Steel Design.”
Problem. Consider the following problem. Find the displacement of node 4. Assume F2=200 N, F3=300 N, F4=400 N and Kı= 100, K2= 200, and K3= 300 N/mm. F. 3 2 3 4 Note: The stiffness matrix of individual springs should be first written, then the equilibrium equations at each node should be written, expanded in terms of nodal displacement, and used to perform the assembly of the global stiffness matrix of the problem. Then, the appropriate boundary conditions should be applied and the nodal displacement vector should be found. Every step should be shown; missing any step would result in point deduction even if the final answer is correct.
Q: For the spring system shown in the accompanying figure, determine the displacement of each node. Start by identifying the size of the global matrix. Write down elemental stiffness matrices, and show the position of each elemental matrix in the global matrix. Apply the boundary conditions and loads. Solve the set of linear equations.
