This book presents, in a uniform way, several problems in applied
mechanics, which are analysed using the matrix theory and the properties
of eigenvalues and eigenvectors. It reveals that various problems and
studies in mechanical engineering produce certain patterns that can be
treated in a similar way. Accordingly, the same mathematical apparatus
allows us to study not only mathematical structures such as quadratic
forms, but also mechanics problems such as multibody rigid mechanics,
continuum mechanics, vibrations, elastic and dynamic stability, and
dynamic systems. In addition, the book explores a wealth of engineering
applications.
