Question
Modal analysis was done on a device by computional methods. The first natural frequency of the device is 300 hertz with a mode shape where the device moves sinusodually on the x y plane. Inside the device on the x z plane there is a rotating imbalance operterating at 300 hertz. Will the rotating imbalance cuase resounance?

    Please explain every step as clearly and detailed as possible. B Frequency Response Modeling Frequency response modeling of a linear system is based on the premise that the dynamics of a linear system can be recovered from a knowledge of how the system responds to sinusoidal inputs. (This will be made mathematically precise in Theorem 13.) In other words, to determine (or iden- tify) a linear system, all one has to do is observe how the system reacts to sinusoidal...

    10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
