Eng Dynamics app provides real homework and test problems for the common engineering course called Dynamics. All problems are organized in sections and chapters common to most textbooks. Each problem has a complete solution with graphics to help you better understand how to solve the problem. Also, each problem has a link to a theory web page for that section at the online eBook (eCoursesBook.com). There is no cost for the online eBook, and it can be accessed outside of the app.
The Lite version (free) of the app has a select number of problems, about 50-70. The Pro version ($3.99) has over 400 problems. Neither has ads. Both versions use the internet to pull problems from an online database as needed. Network connection is required to run the app. Each problem is small (less than 20 k) and are vector-based graphics.
All problems have been used in real engineering classes. Problems are accessed through an online database, so if any errors are identified, they will be updated and the app will use the corrected version. This program is copyrighted and cannot be distributed without the authors written consent.
