The results of an experimental study of a magnetically-kicked flexible-beam oscillator are presented. The dynamics of the autonomous system are observed using nine strain gauges distributed along the length of the beam. The Karhunen-Lo{grave e}ve decomposition is used to study the dimensionality of the system in terms of modal interactions. Two modes which interact to produce the observed dynamics over a wide range of the system{close_quote}s bifurcation parameter are found. It is concluded that a two degree of freedom model is adequate to describe the observed steady-state phenomena. {copyright} {ital 1996 American Institute of Physics.}
