Two identical mass-spring systems, A and B, with different damping ratios are driven by an external force with a variable frequency. The phase difference between the drive force and the displacement of the system is plotted as a function of the drive angular frequency and is shown below for both A and B. Which of the statements below is correct? 3.0 Phase Difference (rad) 1 0.5 A B 0.0 4 Q 0 Driver Frequency (rad/s) Show Transcribed Text D Select one: The damping ratio of A is less than that of B and the resonance for both systems has an angular frequency of approximately 2.5 rad/s. The damping ratio of A is less than that of B but the angular frequency of the resonance for both systems cannot be determined from the plot. The damping ratio of B is less than that of A and the resonance for both systems has an angular frequency of approximately 2.5 rad/s. The damping ratio of B is less than that of A but the angular frequency of the resonance for both systems cannot be determined from the plot. The damping ratio of A is less than that of B and while the resonance for A has an angular frequency of approximately 2.5 rad/s, B does not show a resonance.

Refer to the problem of the two coupled oscillators discussed in Section 12.2. Show that the total energy of the system is constant.
