MECHANISMS AND MACHINES: KINEMATICS, DYNAMICS, AND SYNTHESIS has been designed to serve as a core textbook for the mechanisms and machines course, targeting junior level mechanical engineering students. The book is written with the aim of providing a complete, yet concise, text that can be covered in a single-semester course. The primary goal of the text is to introduce students to the synthesis and analysis of planar mechanisms and machines, using a method well suited to computer programming, known as the Vector Loop Method. Author Michael Stanisic's approach of teaching synthesis first, and then going into analysis, will enable students to actually grasp the mathematics behind mechanism design. The book uses the vector loop method and kinematic coefficients throughout the text, and exhibits a seamless continuity in presentation that is a rare find in engineering texts. The multitude of examples in the book cover a large variety of problems and delineate an excellent problem solving methodology.
- A large number of automotive-based examples are included in the text -- these examples are a highly engaging feature for students.
- This is the only text that consistently uses the Vector Loop method throughout the text.
- Subject matter presented entirely in terms of kinematic coefficients, including geartrains, mechanical advantage, limit positions and dead positions.
- Final two chapters deal with mechanism synthesis and stand apart from the first seven chapters which focus entirely on analysis.

"I believe that the authors are doing an excellent job of paying attention to the audience. Considering that this text is meant for a junior level course, I particularly enjoy that there are sections where the authors are not holding the reader's hand throughout the discussion which will force the reader (student) to think about what exactly is going on. But when fundamental concepts are introduced, there is a very thorough explanation accompanied by detailed examples that would be useful for a student seeing the material for the very first time."
"The approach of using synthesis to motivate the study of analysis is meritorious. The vector loop and kinematic coefficient theory that is utilized throughout is modern and well suited to software implementation. This appeals to me as a user of such a text."
