Compare the measured and calculated resonance frequency of the forced oscillator. Also determine the spring constant k of the spring and viscous damping coefficient. Use the values specified in Exercise 2.7 A.
Answer: Resonance frequency (theoretical) $f_{res}$=1,146Hz
Resonance frequency (experimental) $f_{res}$=1,144Hz
Spring constant k=18,5 N/m
Viscous damping coefficient β=7,963 g/s
