This paper presents a general structured procedure using eight steps to solve machine design problems. The design of a circular shaft subjected to combined loading is presented to show the general structured procedure. All equations are formulated symbolically and solved using a modern engineering tool. One significant advantage is that symbolic equations can be solved for any variable value. Therefore, the design process generally requires solving problems over a range of variable values to obtain a satisfactory design. An essential part of our approach is educating our students to question, test, and verify “answers” to all of their problem solutions. Verifying answers is done by developing and implementing test case scenarios to verify the problem’s validity. Lecture examples and homework problems throughout the course are solved with all equations formulated symbolically, and test cases are used to verify the equations. The circular shaft design project is divided into multiple phases. Each phase of the project requires the material covered up to a point in the course. A project phase is assigned once a topic is covered in the lecture, and reinforced through homework and quizzes.
