    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?

    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?

    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.

    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?

    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...
