- Textbook and Workbook for this class: Principles of Engineering, by Handley, Coon, Marshall, ISBN 978-1435428362 Amazon link Note: There are different ISBN's for this book, because it is used in many foreign countries, and some are paperback and some are hardback. As far as I can tell, they have the same contents. 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 Amazon link The workbook has (14) chapters and is around 180 pages in length. There are lots of used copies of these books online.
- Supplies: You will need a scientific calculator Amazon link, and various types of graph paper throughout the course Printfreegraphpaper.com.
- CAD: Fairly early in the course, you will need to download AutoDesk Inventor (the full version). It's free, but you will need proof that you're a student, and not just someone trying to get free software. This is usually not a problem for homeschoolers, but email me with any questions. AutoDesk Student link
- You will need access to a relatively modern computer with internet connection. A computer less than 5 years old should suffice. You will need a webcam and mike to participate in the class.
- Homework: You'll be turning in your homework on Canvas. You will receive a join code.

Unit 1: Machines & Mechanisms
Ch. 3: The Mechanical Advantage
What are we learning?
We'll dive into simple and compound machines, and an important engineering concept called "mechanical advantage".
Below: Steam engine. The flywheel was hooked up to a drive belt, which delivered power to other machines in the factory

Ch. 4: Mechanisms
What are we learning?
Now we graduate to more-complicated mechanisms, such as linkages, cams, and bearings... and gears, sprockets, and chain drives. These are the building blocks of modern machinery, robotics, wind turbines, car engines, and so on.

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.

Ch. 9: Materials
What are we learning?
In this chapter we learn the properties of the 'classic four' engineering materials: metals, concrete, wood (timber), and masonry; plus modern materials such as polymers and composites.
In the next chapter we'll calculate stress & strain, and analyze structural elements for tension, compression, bending, and shear forces that we encounter in real engineering problems.
We'll also start analyzing some modern engineering disasters, starting with the I-35 bridge collapse.
