Homework Help: Principle of superposition

  1. Apr 11, 2008 #1
    1. The problem statement, all variables and given/known data

    Apply the principle of superposition to a beam to calculate or show beam deflection.

    2. Relevant equations

    Maximum Deflection.

    (WL^3) / (48EI)

    Equation for possition two, when possition two is 3/4 or 1/4 of the total beam lengh

    (Cant figure out the above)

    3. The attempt at a solution

    I think i need to sum the two figure, however, cant get a figure for point two.

    Think i need an equation to calculate deflection at a given point?

    Thanks for any help...
