Transcribed Image Text:Engineers can determine properties of a structure that is modeled as a damped spring oscillator, such as a bridge, by applying a
driving force to it. A weakly damped spring oscillator of mass 0.236 kg is driven by a sinusoidal force at the oscillator's
resonance frequency of 28.8 Hz.
Find the value of the spring constant k.
k =
What is the oscillator's damping constant b?
The amplitude of the driving force is 0.505 N and the amplitude of the oscillator's steady-state motion in response to this driving
force is 0.997 m.
