Question

5 Use MATLAB to plot the Bode diagram for the 1-DOF mechanical system in Problem 9.11.Estimate the frequency response for the position input xin(t) = 0.04 sin 40t m by reading the Bode diagram (indicate the frequency response parameters on the plot of the Bode diagram).Obtain a more accurate answer by using MATLAB’s bode command with left-hand-side arguments for computing magnitude and phase angle.
