The Analysis of a Proposed Experiment to Measure the Speed of Gravity in Short Distances

Figure 6

Vibration modes of the broadband detector. The mode on the top all three bars vibrate at the same phase, frequency: 4772 Hz; the mode in the middle the central bar does not vibrate but it oscillates and the side bars vibrate in counter phase, frequency: 5961 Hz; the mode on the bottom the side bars vibrate in counter phase to the central bar, frequency: 7170 Hz. Central bar length equal to 0.63 m and sidebar length equal to 0.3 m. Source: from authors [27].
