Unformatted text preview: of error in your estimation. d) Evaluate the damping ratio. Based on the readability of the chart, which method would you pick? Log decrement or %OS? Why? e) Evaluate the natural frequency. f) Write down the frequency response function for this system, and the corresponding differential equation. ME 365 HOMEWORK 7 Spring 2010 Out: March 4 2010 Due: March 11 2010 3 Problem 3: Consider the frequency response plots shown below. Figures (iii) and (iv) are magnified views of Figures (i) and (ii), respectively, plotted on linear axes. (a) Determine the static sensitivity, K. (b) Determine the natural frequency of this system, n . (c) Use all three methods described in the notes to determine the system’s damping ratio. Compare your results....
