A first course in mechanics should develop a student's ability to analyze and solve problems using well-understood basic principles applied in a simple, logical manner. The emphasis of the 11th edition of Vector Mechanics continues this tradition and focuses on the correct understanding of the principles of mechanics and on their application to the solving of engineering problems. New to this edition, the text employs the SMART Problem-Solving Methodology approach to solving engineering problems - Strategy, Modeling, Analysis, and Reflect & Think. The presentation and methodology is intended to support students applying this approach in all assigned problems. To further support student learning, practical applications are introduced early, new concepts are introduced simply, and fundamental principles are placed in simple contexts. Students are given extensive practice through Sample Problems, special sections entitled Solving Problems on Your Own, and extensive homework problems sets.
