Solution of the D 7 (reference 2) Option 14 Dievskaya V

Termehu Dievskaya VA task 2 task Dynamics 7 (D7) on the theme "small oscillations of mechanical systems":
D7 ACTIVITY 2 - FORCED VIBRATIONS: Mechanical systems in Schemes 1-30 provided with weightless viscous damper, which is set at a point in parallel to the axis of the elastic element, and creates a resistance force proportional to the velocity of point B: R = -bvB, where b = 20 N * s / m - coefficient of resistance.
In addition, the system begins to operate the driving force F = F0sinpt, where F0 - 60 H, p = 25 s-1 - the amplitude and frequency of the driving force. The driving force is applied at the point B and acts parallel to the axis of the elastic element. (If the point coincides with the point A in the diagrams specified in = A)
It is required to determine the amplitude of the purely forced vibrations of the system.
