Introduction to Statics and Dynamics – Andy Ruina and Rudra Pratap – 1st Edition


In 1992 we told a textbook sales rep that we didn’t like the Dynamics books. She said “Write your own.” Most people said “Don’t write a book. It’s too much work, no-one will appreciate it and it will probably lose money.” Saunders contracted the book and then sold it to Oxford. Now it’s ours. Most years we work together for a month or so in Ithaca, Finland, or Bangalore. We re-organized the book 4 or 5 times and added a Statics book because students needed help with vectors and free body diagrams. Various pre-release versions have been used at Cornell and elsewhere about 25 times. It has had about 40 external reviews. The table of contents, preface and introduction show our intentions.

The sections have been divided so that the homework problems selected from one section are usually about half of a typical weekly homework assignment. The theory and examples from one section might be adequately covered in about one lecture, plus or minus.
