Find the absolute$-$acceleration transfer function Hacc$()$ for the foregoing MDOF model

of the earth dam in the last problem under horizontal ground motion if the damping is

modeled by Rayleigh damping with $=0\mathrm{.}051$ and $=\frac{0\mathrm{.}05}{}1$ where $1$ is the fundamental

natural frequency of the model. Plot the amplitude of the absolute$-$acceleration transfer

function for the top degree of freedom as a function of $\frac{}{}1$ and comment.
