Please draw FBD and solve. The solution should be handwritten Only.
3. Draw complete, clearly labeled free-body diagrams. All unknown support reactions should be clearly labeled with a variable name. All known values such as weight or applied forces should be clearly labeled with their known values. Don't need to show equilibrium equations, I just need free-body diagrams. Only solve this text question, not the questions in image.
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.
