A strong conceptual understanding is essential for solving problems successfully. This edition of vector mechanics for Engineers helps instructors and students achieve this goal by providing strong understanding and logical analysis for solving problems using SI metrics. With new concepts presented in a simplified and detailed manner, a number of advanced or specialty sections are included. To keep these distinct and optional, they are marked with asterisk so users can choose whether or not to read. The text adopts smart (strategy, modeling, analysis, reflect and think) approach to problem solving. Maintaining its sound and significant pedagogy, approximately 300 homework problem sets are introduced or revised. The book is accompanied with rich online resources for instructors.
