Changes from Previous Offering

1. Change of textbook from RC Hibbeler, Mechanics of Materials (11th edition) to RC Hibbeler, Statics and Mechanics of Materials in SI Units, Global Edition with Mastering in Engineering.  The interactive, self-paced tutorials in the textbook which the convenor has been formally invited to review and develop provide individualized coaching to help students stay on track. With a wide range of activities available, students can actively learn, understand, and retain even the most difficult concepts. The text and Mastering Engineering work together to guide students through engineering concepts with a multi-step approach to problems and will provide students with plenty of practice examples to improve results. 

Changes in Response to Student Feedback

2. Remedial lessons will be provided for students who fail the diagnostic quiz. To help students appreciate the expectations of the solutions presented in quiz and exam, examples of good and poor solutions will be presented in lecture 1 and throughout the semester.
