The resonance of the Wilberforce pendulum and the period of beats

The resonance of the Wilberforce pendulum is defined as the state of the maximum period of beats. The plausible assertion that resonance is characterized by the equal values of both the frequencies of longitudinal and torsion vibrations is proven. Although a coupling constant between longitudinal and torsion vibrations determines the frequencies of normal modes it plays no role in the definition of the resonance state.
