1. The problem statement, all variables and given/known data For the system of springs a) Assemble the stiffness matrix K and the force-displacement relations, K*u = f b) Find the L*D*L^T factorization of K. Use Matlab to solve c) Use the boundary conditions and applied forces to find the displacements 2. Relevant equations 3. The attempt at a solution I'm getting stuck on part c My confusion lies in why is F = <10 10 10>^T? I don't see were these 10 values came from. Thanks for any help!
