Forced vibration of SDOF system
Which of the following is a forced vibration system?
Under static condition due to an operating force if a 10N/m stiff 10kg system undergoes a deflection of 10cm, what is the amplitude of force ?
What is the governing equation for forced vibration system with harmonic excitation ?
Solution of forced vibration system consists of

The above equation gives the steady state amplitude for a system excited by an external harmonic force.
