Vibrating Systems

Physical systems that vibrate will do so at one or more unique frequencies. In this chapter you will learn about simple harmonic motion, vibrating systems, complex vibrating systems, and you will be introduced to vibration in musical instruments.

To successfully complete this chapter you should...

  • Read chapter 2 in your text book (pages 19 - 32).
  • Carefully study the important concepts.
  • Be able to determine the frequency of vibration for simple harmonic motion of different systems.
  • Be able to describe the motion of complex vibrating systems as harmonic or non-harmonic.
