Principles of Engineering

Course outline and study materials provided below.
Picture

Textbook and Workbook for this class: Principles of Engineering, by Handley, Coon, Marshall, ISBN 978-1435428362. Note: There are different ISBN's for this book, because it is used in many English-speaking, foreign countries, and some are paperback and some are hardback. As far as I can tell, they have the same contents, however. Make sure the textbook you are buying has (14) chapters. The accompanying workbook is Principles of Engineering (Workbook), by Singer, Phillips, French, ISBN 978-1435428379. The workbook has (14) chapters and is around 180 pages in length. There are lots of used copies of these books online. 

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 once we get going, 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.

Utility Shed Energy Project
Compute the heat loss from the Utility Shed in BTU/hr, assuming inside temp. 70 F and outside temp. 32 F. Then do a separate "energy efficient" design with 2"-thick molded polystyrene under the concrete slab, and re-compute the BTU/hr. Use a soil temp. of 55 F. Report your results in the "Energy Worksheet Excel Template" and turn it in on Canvas. The Powerpoint slides, shed dimensions, and R-values chart are posted below.

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.
  • Electric cars, electric trucks, electric airplanes
  • Wind power
  • Solar power
  • Nuclear power, micro-reactors
  • Personal robots, flying skateboards, weird scooters
  • Self-driving automobiles
  • Travel to Mars, Space-X, the world's largest rocket
  • Tissue engineering
  • Analyze a well known skyscraper, bridge, or tunnel
  • Analyze an engineering disaster
  • Showcase something on Inventor
