ABSTRACT
Annotation. The general concepts of the parametric excitation of a linear system
and the conditions necessary for parametric resonance are considered in Chapter 5,
in which we examine the square-wave modulation of a parameter. The present
chapter deals with another case of parametric excitation of a linear torsion spring
oscillator, namely that of excitation arising from a smooth, harmonic motion of
the weights along the rod of the flywheel.
