Course Outline
The course is organized into sixteen (16) lessons below. In the 2-semester class, we will spend an average of 2 weeks on each lesson. The due dates for the homework and projects will be clearly stated in Canvas - as well as your weekly class emails - as we progress through the course, so you will always know when things are due. As tempting as it might be, do not 'work ahead', because the assignments often get modified as we go along.

Week 7: Exercise 4.2 Calculating Gear Train Speed and Torque Ratios Week 8: Gears, Pulley Drives, and Sprockets problems (below) Week 8: Inventor "Oldham Coupling" project - Disk, Flange, Shaft, and Key parts (below). Try to do all 4 parts, or do what you can. AutoDesk Inventor: I have explained how to download Inventor several times, including the fact that you need a "school" on the approved list, and I've shown you twice how to use Inventor to create simple parts, and several of you have already downloaded the software and begun using it. The instructions for the Oldham Coupling are complete and step-by-step, and are easy to follow. Let me know if you run into any problems.

Final Class Presentations
Choose an engineering topic of interest, prepare an 8-10 minute PowerPoint, and present it at the final class. Submit your "topic" via email for pre-approval by the due date. Include lots of pictures, diagrams, and charts. Use note cards if you must, but DO NOT READ FROM YOUR SLIDES! You will need a minimum of around 10-15 slides to talk for 8-10 minutes. Be ready to take questions from the audience! Topics are numerous! We have covered a lot of ground this year, and something has piqued your interest.
