A bench for resonance vibrations includes vibrational system arranged as two normal to each other vessels filled with liquid, two membranes connected with rigid rod, restricting ends of one of the vessels, and generator of vibrations of liquid. To simplify construction and to increase accuracy of setting resonance vibrations, second vessel is closed with hermetic cover and generator of liquid vibrations is arranged as metal spiral placed to the second vessel and connected to source of alternating current. |
