Digital Affordable Learning Solutions (ALS) provides students with quality yet affordable educational content and enables instructors to utilize multimedia and interactive technology as effective ways of delivering course material. The reduced course content expenses not only allow more students to access the educational material, but also permit the instructors to customize and adapt the material to their teaching style. Incorporation of interactive technology through visually appealing media such as animations, graphics, simulations, videos, and three-dimensional models promotes students' interest in learning theoretical and abstract subjects in science and engineering. In this study, the incorporation of an interactive eBook as an affordable learning solution in Mechanics of Materials is discussed. Features offered in the eBook include responsive three-dimensional models, animations, lecture videos, course summaries, algorithmically generated problem sets, pop-up hints, and guided steps. Such an eBook provides various avenues for students to learn and practice concepts, and has yielded very encouraging results, including increased student performance and positive feedback from the students themselves. The presented interactive eBook has the potential to inspire other educators and course designers to develop and implement interactive tools in their pedagogical approach.
