I read the fourth edition, which combined statics and dynamics all neatly packed into 926 pages! Statics was phenomenal and I soaked up an amazing amount that quarter. Dynamics, not so much. Maybe because the topics is more challenging than Statics. Good job Beer & Johnston (E. Russell Johnston, Jr. - co-author).
Better be at the top of your game to try this textbook on your own. Before trying this book you should have completed statics, the analysis of bodies at rest. When I took Dynamics at NIU, I used this book to enhance my understanding. I don't think I could have gotten through this book without a professors guidance in the class.
