Find the steadystate motion of a damped harmonic oscillator that is driven by a periodic square wave force with a frequency w equal to 1/3 the natural frequency of the undamped oscillator. Note that you don't really need to use the physlet above: it's only there for your reference. Define the driving force in the following way: F(t) = F_{0}/2 for 0 < wt < p, 2p < wt < 3p, etc. F(t) = F_{0}/2 for p < wt < 2p, 3p < wt < 4p, etc 1. Show that the Fourier series expansion for the driving force is: 2. Find the relative amplitudes for the first 3 terms of the response function x(t). Let the quality factor Q = 100.
