6.7 Write a MATLAB script (M-file) that executes the Simulink simulation for the mechanical system in Problem 6.6 for input frequencies ranging from ? = 1 rad/s (0.16 Hz) to ? = 100 rad/s (15.92 Hz) in increments of 1 rad/s. Store the ratios of the output/input amplitudes but use only the last one-third of the simulation response data (the so-called steady-state response) for each input frequency [Hint: to do this, compute the ratioxend/xn by using the command max (x_end) /max (x_in) where x_end is the last one-third of the system response x(t)]. Plot the output/input amplitude ratio vs. input frequency, and based on your plot, summarize how the mechanical system's displacement response x(t) varies with input frequency o. This problem is an example of a system's frequency response, where the system input is a periodic function (such as a sinusoidal input function)
