Overview
Wickert/Lewis’ “An Introduction to Mechanical Engineering,” 5th Edition with WebAssign introduces first- and second-year students to the ever-emerging field of mechanical engineering.
Balancing design and engineering analysis within the context of hardware and modern technologies, this edition helps students gain appreciation for how engineers design hardware that builds and advances societies worldwide. With nearly 300 photographs and illustrations bringing these concepts to life, students strengthen problem-solving skills while exploring core mechanical engineering principles.
This edition helps you provide your students with an exciting view of what to expect in their program and future careers. By learning about mechanical engineers, what they do, and the impact they have, students develop a solid foundation in sound engineering analysis, technical problem-solving, and design skills.
- AI-powered Student Assistant in WebAssign provides real-time, course-aligned support to students directly within their learning experience.
- Expanded homework sets include 130 homework problems at different levels of difficulty, grouped by section in each chapter to reinforce key concepts.
- WebAssign is Cengage's learning platform that helps you deliver a high-impact, guided learning experience to prepares students for what's next.
- Students learn about designing functional items that are cost-effective to manufacture, safe to use, and responsible in terms of environmental impact.
- Students use calculations, estimates, and approximations that mechanical engineers perform as they solve technical problems and communicate results.
- Focus On boxes, vignettes, and case studies highlight interesting topics, accomplishments, challenges, and other emerging concepts in mechanical engineering.
- Students explore recent global, technological, environmental, and social applications, including commercial space flight, developing fields, and more.
- The authors’ accessible writing style motivates students and offers a glimpse of what they’ll study in later courses and practice during their careers.
