Homework Help: Cantilever beam virtual work

  1. Feb 1, 2013 #1
    1. The problem statement, all variables and given/known data

    see attachment

    2. Relevant equations

    3. The attempt at a solution

    I think #1 is to find the bending moment equation, then use the principle of virtual work. I have no idea how to find the bending moment equation and which principle of virtual work to use. Any guidance would be appreciated.

    What about the shear force? Can you find shear from the given distributed load?

    Have you studied any strength of material?

    Do you have a working definition of 'bending moment'? Are you able at least to calculate the total load? Answers to these 2 questions would be a valuable starting point, in addition to SteamKing's suggestion.
