We consider the dynamical inverse problem for a special kind of a two velocity system. The system describes the vibrations of a composite beam formed by two connected beams and we recover the shearing stiffness coefficient. The vibrations of the beam are generated by the control applied to the end of the beam. The inverse data are the response operator and the dynamical measurement at the other end of the beam.
