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
0.246
kg is driven by a sinusoidal force at the oscillator's resonance frequency of
27.8
hz. find the value of the spring constant.
the amplitude of the driving force is
0.543
n and the amplitude of the oscillator's steady‑state motion in response to this driving force is
0.877
m. what is the oscillator's damping constant?
