Static deflections of the platform alone, the platform with
the DVA, and the DVA were first recorded as reference points.
The voltage was then first swept over the range of available
values (1.25-11.75V) in increments and the displacement
amplitude of the platform alone were taken by holding a ruler
parallel to the base and stopping it at the point where the mass
stopped contacting, which was marked and measured on the
frame. This provided the experimental reference data for the
1DOF system that we attempted to stop at resonance.
