Generalizations of the Faraday problem in mechanical system "reservoir–liquid with a free surface"
Two generalizations of the classical Faraday problem on development of parametric resonance in mechanical system "reservoir – liquid with free surface", namely, the effect of supplementary degree of freedom, i.e., possibility of horizontal motion of reservoir due to transversal motion of free surface of liquid, and effect of supplementary degree of freedom, i.e., possibility of angular oscillations of reservoir, which is suspended as pendulum, due to transversal oscillations of a free surface of liquid.
