Rezensionen
From the reviews: "This text provides an excellent introduction to the wide range of topics required in vibration and acoustic engineering. ... It allows the working engineer to get good in depth coverage of the features without the excessive details other texts have. I recommend this book for the practicing engineer as well as students, it meets its purpose of providing the theory as well as practical applications for mechanical and acoustics vibrations of dynamic systems and how that applies to spacecraft design engineering."
