For Lab number 4 Structural Dynamics Analysis, For this experiment, we limited our analysis of the structure’s frequency response to the spectral domain of 200 Hz. Did you note any peaks in the transfer function at frequencies beyond this limit? Why do you think we limited our analysis to relatively low frequency responses? Explain.
Offer a possible explanation for the existence of more than a single natural frequency for the space truss. (HINT: Do you think the structure is limited to a single type (or mode) of vibrational response? In addition, you may want to look up the term modal analysis.)
