I'm a postgraduate majoring in aeronautics. I think this book is generally suitable for those who have interest in aircraft structure but do not necessarily have educational backgrounds in related fields. In fact, although the emphasis of my study has always been one of aerodynamics rather than structural design, I found little new in this book to learn after reading it cover to cover. If you have taken course modules such as Mechanics of Materials, Structural Mechanics back in college then there really isn't any need for you to pay for this book. But if you've just begun to study aeronautics and haven't quite decided what to do after graduation this can make an enjoyable introduction to Structural Design and Stressing. In such cases it is my suggestion to borrow it from your library, like I did.
