Unformatted text preview: 2009-03-0513Review Questions: Chap. 2Review Questions: Chap. 21.What is the physical meaning of homogeneous and particular solutions to the forced, underdamped, single degree-of-freedom mechanical oscillator model?2.What is the frequency of the response of a viscously damped system when the external force is Fsin (t) ? Is this response harmonic?3.Why is the damping considered only in the neighborhood of resonance in most cases?4.Is it true that the amplitude and phase of free response of a forced, viscously damped oscillator can be determined from the initial conditions without considering the steady response?the initial conditions without considering the steady response?5.Is it true that a constant force on the vibrating mass has no effect on the steady-state vibration?6.What are the amplitude and the phase angle of the response of a viscously damped system in the neighborhood of resonance?...
