Derive Euler–Bernoulli equation from Navier-Cauchy equations

  1. Sep 11, 2015 #1

    Is it possible to derive the Euler–Bernoulli equation:
    [tex]\frac{d^2}{dx^2} \left(EI \frac{d^2w}{dx^2} \right) = q [/tex]
    from Navier-Cauchy equations:
    [tex]\left( \lambda + \mu \right)\nabla\left(\nabla \cdot \textbf{u} \right) + \mu \nabla^2\textbf{u} + \textbf{F} = 0[/tex]

    I don't really know where to start because the Navier-Cauchy equations are 3 equations but the Euler–Bernoulli equation is just 1 equation.
