Find the eigenvalue and eigenvector












0












$begingroup$


Can someone give me some guidance on how to obtain the eigenvalue and eigenvector for the following equation? Don't I need another equation?



$EIu_{yy}+pu=0$ where $lambda=frac{p}{EI}$

    $lambda$ does not appear in the equation? Also, you would need some boundary conditions.

Write it as



$$
frac{{rm d}^2u}{{rm d}y^2} = - lambda u
$$



And try solutions of the form



$$
u(y) = A e^{pm isqrt{lambda}y}
$$



Eigenvectors are $u$ and eigenvalues are $lambda$
