216 LESSON 25. HARMONIC OSCILLATIONS
Figure 25.2: The amplitude of oscillations as a function of the frequency
of the forcing function, α, as given by (25.29), is shown for various values
of the damping coefficient b = 1, 0.3, 0.1, 0.03, 0.01 (bottom to top) with
ω = 1.The oscillations resonate as α → ω.
