Homework Help: Finite Element analysis: Free body diagram help

  1. Apr 9, 2013 #1
    1. The problem statement, all variables and given/known data
    Hey guys, my problem is not really the end solution, but the preliminary step that I'm not too sure about. Given the following diagram:


    The image on the left is the given model, and the right image is my nodal element FBD, but somehow i dont believe that's correct. Can you guys help me out with this?

    3. The attempt at a solution

    The question asks to derive the spring constants for the model, but to do that i need to get the diagram above correct.

    Any help you guys can provide is appreciated. Thanks!
