WileyPLUS is an interactive online teaching and learning environment that engages engineering students with course material beyond the classroom. Automatically graded problems, many with algorithmically generated values, enable students to practice and master the topics and concepts. In addition, relevant and timely learning resources provide students with the tools they need to better understand key concepts and succeed in the course and in their careers.

- Secure solutions - Almost 1,200 algorithmically generated homework problems reduce student cheating on assignments
- 24/7 learning support - WileyPLUS provides positive intervention when you can’t! WileyPLUS provides help as students are working on assignments, including:
- Video solutions: whiteboard and audio walk through how to solve a similar problem
- Video tutorials: whiteboard and audio of how to use common mathematical functions to solve problems
- Animated illustrations: illustrations from the text (including Free Body Diagrams) are developed in real time
- What an Engineer Sees: shows how an engineer would solve a real-world problem
- Technical accuracy - this course retains Meriam and Kraige’s commitment to rigorous accuracy-checking
- Reading support - students are encouraged to read the text via direct links from problems to the appropriate text content and gradable concept questions
- Easier for students to show work - students can attach photographs or scans of hand-written files or use the built-in whiteboard feature
