Description

15. helical spring stiffness k = 10 N / m sinker suspended mass m = 10 g, and the whole system was immersed in a viscous medium. Taking the drag coefficient b is equal to 0.1 kg / s, determine: 1) the frequency of natural oscillations ν0; 2) the resonant frequency νpez; 3) the resonant amplitude Arez, if the driving force varies harmonically and its peak value F0 = 0,02 H; 4) the ratio of the resonance amplitude to the static displacement by the force F0.
