8. Body weight m = 1 kg is in a viscous medium with a resistance coefficient b = 0.05 kg / s. By means of two identical spring stiffness k = 50 N / m each body is held in an equilibrium position, a spring is not deformed (Figs.). Body displaced from its equilibrium position and released. To determine: 1) the damping coefficient d; 2) the oscillation frequency ν; 3) the logarithmic decrement Θ; 4) the number N of oscillations, after which the amplitude decreases by a factor e.
Detailed solution. Decorated in Microsoft Word 2003. (Target decided to use formula editor)
