Macmillan Learning 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 0.238 kg is driven by a sinusoidal force at the oscillator's resonance frequency of 36.6 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 0.585 N and the amplitude of the oscillator's steady-state motion in response to this driving force is 0.855 m. N/m b = kg/s
