Strangely, when I make "emould" 10^3 times bigger to 2.0e8, I got the frequnce response plot with the same resonance frequency, like below, but the amplitude is 10^3 times smaller, as we can see from the plot. I have the same excitaion force, both 10N. Even if I made a mistake for the unit of Emodul, the Amplitude at resonance frequnce shouldn't 10^3 times smaller right?
