The amplitude of the driving force (red arrow) is the same for all damping but will appear different because the scale on the left changes to match the amplitude of the center mass.

The grey dots show the maximum displacement of each of the masses for a given amount of damping but note that the scale on the left changes depending on amplitude. How does the damping coefficient affect the maximum displacement of the center mass (look at the scale on the left for different values of damping)?
