Question:

For a single-degree-of-freedom spring-mass-damper system subject to forced harmonic vibration, the measured FRF is displayed in Figs. P6.1a and P6.1b. Using the peak picking method, determine $m$ (in $\mathrm{kg}$ ), $k$ (in $\mathrm{N} / \mathrm{m}$ ), and $c$ (in $\mathrm{N}-\mathrm{s} / \mathrm{m}$ ).
