I am working on a lot of things with electric motors, and many other electromechanical devices. Any text book comes to mind?
Hello OldEngr63: I am writing to you just to let you know that finally, after many... many... many emails, I could buy one new copy to an online bookseller... was a hard negotiation!!!SuperDaniel, thanks for the endorsement on Crandall, et al. I think it is one of the most important textbooks I have every found, and I have two copies that I guard very carefully!
As to why these books are out of print, the answer is simple: they did not sell well. Publishers don't give a rip about the significance of a book; their concern is purely with the $$$. Crandall, et al. requires that a person be willing to work with the calculus of variations; they give an excellent intro to the topic, but you do have to plan to work at it. This frightens most folks away. White and Woodson is also a very important book, but it is not nearly as well written for a student as is the book by Crandall, et al. It did exceptionally poorly in the market and disappeared very quickly, even though it was unique in its day for the treatment of the material covered.
