1. ### Finding Omega and Zeta from a Magnitude and Phase Plot

Yes, I am assuming that the AFM cantilever is being modeled as a second order system. With the cantilever tune, the phase curve is set to 90° of the resonant frequency. So would I be close enough in estimating that the natural frequency is 72.7 kHz?
2. ### Finding Omega and Zeta from a Magnitude and Phase Plot

I was able to calculate the value for the damping ratio; but I am having trouble finding the value of the natural frequency. Any ideas on how to solve for the natural frequency?
3. ### Finding Omega and Zeta from a Magnitude and Phase Plot

Could you elaborate? Where does this -3dB bandwidth come from? Is Q inversely related to the damping ratio, ζ? Thanks for your help.
4. ### Finding Omega and Zeta from a Magnitude and Phase Plot

Homework Statement I've been asked to estimate ωn and ζ from the magnitude and phase plot of an atomic force microscope. The magnitude and phase plot is attached. Does anyone know how to solve for these values?
5. ### Calculating Transformer Input Voltage?

The load is 1.5Ω, and Xm is also in Ω.
6. ### Calculating Transformer Input Voltage?

Homework Statement A 2400/240-V, 60-Hz transformer has the following parameters in the equivalent circuit of Figure 6.5: the high-side leakage impedance is (1.2+j2.0)Ω, the low-side leakage impedance is (0.012+j.02)Ω, and Xm at the high-side is 1800 . Neglect Rhe. Calculate the input voltage...
