Module 9 : Forced Vibration with Harmonic Excitation; Undamped Systems and resonance; Viscously Damped                    Systems; Frequency Response Characteristics and Phase Lag; Systems with Base Excitation;                    Transmissibility and Vibration Isolation; Whirling of Shafts and Critical Speed.
Lecture 1 : Harmonic vibration of single DOF system
 
Recap
  In this lecture you have learnt the following
Solution to the equation for the forced oscillations
Magnification factor ie ratio between the deflection due to force when applied as sinusoidal vs static
                                                                     
Effect on vibrations due to change in ratio of the forced frequency to natural frequency of the system
