The coincidence of the excitation and resonant frequencies is sufficient to create resonances only for a 1-DOF (one degree of freedom) mechanical system. For multi-DOF mechanical systems, this condition is necessary but may not be sufficient. The spatial distribution and orientation of the oscillating forces is important as well. This is important for many practical applications and therefore should be taken into account by design engineers to avoid potential failures with new projects.
