What are the basic lumped elements of
(i) A mechanical system?
(ii) An electrical system?
Indicate whether a distributed-parameter method is needed or a lumped-parameter model is adequate in the study of following dynamic systems:
(a) Vehicle suspension system (motion)
(b) Elevated vehicle guideway (transverse motion)
(c) Oscillator circuit (electrical signals)
(d) Environment (weather) system (temperature)
(e) Aircraft (motion and stresses)
(f) Large transmission cable (capacitance and inductance)
