Document Summary

Study of oscillatory motion of elastic bodies and the forces associated with them. Vibrations are described as periodic oscillations ie. any motion that repeats itself after an interval of time. Elements of walking, speech, stringed instruments, wind instrument etc. Consider a pendulum period constant regardless of amplitude (function of length) Units will differ: resulting time constants of systems will differ. Interesting thermal energy does not have a through type energy storage element: thermal energy does not oscillate. Traditional design was massively rigid so as to minimize motion to near zero (observable). Current design makes use of flexible structures but is designed with deflection in mind.
