Hi, as part of my engineering degree I am faced with the following problem. I was hoping someone could give me some guidance. I have a basic understanding of matrices, eigenvalues & eigenvectors.

''Write a short essay approximately 2 pages (for a first-year engineering class). Explain

the application of Eigenvalues and Eigenvectors to estimate the modes

of vibration for a structure under a disturbance such as earthquakes''

Any help will be appreciated.
