Preface Preface

Engineering Statics: Open and Interactive is a free, open-source textbook for anyone who wishes to learn more about vectors, forces, moments, static equilibrium, and the properties of shapes. Specifically, it is appropriate as a textbook for Engineering Mechanics: Statics, the first course in the Engineering Mechanics series offered in most university-level engineering programs.

This book’s content should prepare you for subsequent classes covering Engineering Mechanics: Dynamics and Mechanics of Materials. At its core, Engineering Statics provides the tools to solve static equilibrium problems for rigid bodies. The additional topics of resolving internal loads in rigid bodies and computing area moments of inertia are also included as stepping stones for later courses. We have endeavored to write in an approachable style and provide many questions, examples, and interactives for you to engage with and learn from.

Feedback.

Feedback and suggestions can be provided directly to the lead author Dan Baker via email at dan.baker@colostate.edu, or through the Engineering Statics Google Group. We would also appreciate knowing if you are using the book for teaching purposes.

Access.

The entire book is available for free as an interactive online ebook at https://engineeringstatics.org. While the interactive version works best on larger screens, it will also work smartphones but with some limitations due to limited screen width. A non-interactive PDF version, suitable for printing or offline reading on a tablet or computer, is available at https://engineeringstatics.org/pdf/statics.pdf. The PDF is searchable and easy to navigate using embedded links.

The source files for this book are available on GitHub at https://github.com/dantheboatman/EngineeringStatics.

History.

This book began as the vision of a handful of the authors to create a free textbook filled with interactives instead of static figures. Spurred into action by funding opportunities in the Fall of 2018, the team worked on the book through 2019 and launched this working draft version in Fall 2020. Over the two years of creating the book, our team grew to a coast-to-coast representation of large public universities, small private colleges, and community colleges.
