(a) The response times of all assemblies to an electrical input show fast reaction, with the deflection process slowing down towards the maximum possible angles. (b) The graph of the maximum possible deflection α(f) shows a nonlinear correlation with the duration of excitation. Below a cycle frequency of 0.5 Hz, the maximum values are reliably achieved.
