The Mastering Revision consists of new features to help your students build stronger conceptual understanding and problem-solving skills: New - Setup-and-Solve exercises that step students through the problem-solving process, similar to what instructors model during class. This reinforces conceptual understanding of the process applied in approaching the problem and mirrors what students will be expected to do on a quiz or test.New - Enhanced End-of-Chapter Exercises (20% now enhanced) that offer hints and wrong-answer feedback as students work through problems and provide instructional support when and where students need it. New - Pearson eText, a simple-to-use, mobile-optimized, personalized reading experience available within Mastering Engineering. It lets students highlight, take notes, and review key vocabulary all in one place — even when offline. Seamlessly integrated videos and other rich media engage students and give them access to the help they need, when they need it. Educators can easily share their own notes with students so they see the connection between their eText and what they learn in class.Interactive figures that provide new interactivity and are embedded into Pearson eText to help students visualize course concepts that are difficult to comprehend from static images. Together, the Mastering Revision and Engineering Mechanics, 14th Edition provide:   Key author content that enhances conceptual understanding Each chapter is organized into well-defined sections that contain an explanation of specific topics, illustrative example problems, and a set of homework problems. Free-Body Diagrams are emphasized throughout the book. In particular, special sections and examples are devoted to show how to draw free-body diagrams. Homework problems have also been added to develop this practice.Procedures for Analysis provides students with a logical and orderly method for applying theory and building problem-solving skills. A general procedure for analyzing any mechanics problem is presented at the end of the first chapter, and each procedure is customized for specific problem types covered throughout the book.Examples follow the direction of the Procedure for Analysis, in order to illustrate its application. The many examples throughout show how to solve problems ranging in difficulty. They also illustrate the application of fundamental theory to practical engineering problems while reflecting the problem-solving strategies discussed in associated Procedures for Analysis.Expanded Important Points provide a review or summary of the most important concepts in a section and stresses the most significant points when applying the theory to solve problems.End-of-Chapter Reviews include each important point accompanied by the relevant equation and art from the chapter providing the students a concise tool for reviewing chapter contents.Photos and PhotoRealistic Art are used throughout the text to explain how the relevant principles apply to real-world situations and how materials behave under load. In some sections, photographs show how engineers must first make an idealized model for analysis, and then proceed to draw a free-body diagram of this model in order to apply the theory.   A wide variety of problem types that depict a broad range of engineering disciplines, stressing practical, realistic situations and having varying levels of difficulty Preliminary Problems test students’ conceptual understanding of the theory. Preliminary Problems solutions require little or no calculation and are intended to help students develop a basic understanding of the concepts before they are applied numerically.Fundamental Problems offer students simple applications of the concepts and provide the opportunity to develop their problem-solving skills before attempting to solve the standard problems that follow.Conceptual Problems are intended to engage the students in thinking through a real-life situation as depicted in the photo. These analysis and design problems appear throughout the text, usually at the end of each chapter.End-of-Chapter Review Problems now have solutions given in the back, so that students can check their work when studying for exams, and reviewing their skills when the chapter is finished.Free-Body Diagram Problems only require drawing the free-body diagram for the specific problems within a problem set and emphasize the importance of mastering this skill as a requirement for a complete solution of any equilibrium problem.Statics Practice Problem Workbook contains additional worked problems. The problems are partially solved and are designed to help guide students through difficult topics.     Key Mastering features   Teach your course your way Your course is unique. So whether you’d like to build your own auto-graded assignments, foster student engagement during class, or give students anytime, anywhere access, Mastering gives you the flexibility to easily create your course to fit your needs. With Learning Catalytics, you’ll hear from every student when it matters most. You pose a variety of questions that help students recall ideas, apply concepts, and develop critical-thinking skills. Your students respond using their own smartphones, tablets, or laptops. You can monitor responses with real-time analytics and find out what your students do — and don’t — understand. Then, you can adjust your teaching accordingly, and even facilitate peer-to-peer learning, helping students stay motivated and engaged.Learning Outcomes Summaries track student- or class-level performance for both publisher- and instructor-provided learning outcomes. All assignable Mastering Engineering content has been tagged to ABET Learning Outcomes A, E & K. Mastering also enables instructors to add their own learning outcomes and associate those with Mastering Engineering content. Empower each learner Each student learns at a different pace. Personalized learning, including adaptive tools and wrong-answer feedback, pinpoints the precise areas where each student needs practice and gives all students the support they need — when and where they need it — to be successful. Mastering Engineering tutorial homework problems are designed to emulate the instructor’s office-hour environment. Tutorials guide students through engineering concepts in multi-step problems that provide feedback specific to their errors, along with optional hints for breaking down the problems into smaller steps.Wrong-answer feedback, personalized for each student, responds to a wide variety of common wrong answers with immediate feedback specific to their error.Optional Hints provide two types of hints.. Declarative hints give advice on how to approach the problem, while Socratic hints break down a problem into smaller sub-problems.Homework problems support the problem-solving techniques in the text. Answer entry, beyond numerical input, includes:Plotting Mohr’s Circle for a Specific ElementIdentifying Key Points on Stress/Strain CurvePlotting the Shear and Bending Moment Diagrams for a Beam Adaptive Follow-Up Assignments are based on each student's past performance on his/her course work to date, including homework, tests, and quizzes. These provide additional coaching and targeted practice as needed, so students can master the material. Deliver trusted content We partner with highly respected authors to develop interactive content and course-specific resources that keep students on track and engaged. Video Solutions — developed by Prof. Edward Berger, Purdue University — offer step-by-step solution walkthroughs of representative homework problems from each section of the text. Improve student results: When you teach with Mastering, student performance often improves. That’s why instructors have chosen Mastering for over 15 years, touching the lives of over 20 million students.   Learn more about Mastering Engineering.
