Executive Summary
This section is much like an abstract and summarizes the entire report
Introduction
This section should include an introduction of the product and a brief description of group members (i.e. who was responsible for which sections or tasks)
Before Disassembly Section
This circular saw is primarily used for cutting wood. It runs on an AC current, and contains a 2.3 hp motor, turning electrical energy into mechanical energy. At the beginning of the project, it was new, so the group assumed that its initial operation was correct. The saw is operated by engaging a safety switch, and then a power switch. It was very loud, and even without the torque of the blade, kicked back when it was initially operated. This demonstrated the physical power of the motor. The group estimated that the saw would contain about 40 components, and predicted that those components would be made of plastic, steel, aluminum and copper.
Disassembly Procedure
- Document each step to disassemble the product
- How difficult was each disassembly step?
- What types of tools were required to perform this step?
- Include a picture of each disassembly step

After Assembly
Upon reassembling the saw, the group successfully tested it. It ran almost exactly as it had before, but once the switch was disengaged, the motor continued to spin from its momentum. The group surmised that the broken copper wiring in the carbon brushes must have had something to do with the braking of the motor. This problem could be quite dangerous if the lower guard malfunctioned.

Guide to Writing Wiki Code
The beauty about Wiki is that if you don't know the code, you can steal it from someone's page that does. Feel free to click the "edit" links or tabs to view the code for sections or the pages respectively. Be weary about wrecking havoc on another's page. Each page can be rollbacked to a previous verison and your username is linked to all changes. Although you might think it's cool to go through and insert "MIKE RULES" throughout the page, I'm sure Dr. Lewis would not be pleased.
Here's a few tips on writing with Wiki:
This is a bracket "[" "]"
This is a brace "{" "}"
To create a new page/link within Wiki:
- Double brackets, page name, double brackets
- Typing in a new page name will automatically create a page, which when clicked, you can then edit.
- Whatever name you first type in is the name of the page. You can't change page names, only create new pages. Think before you create a new page.
- Don't worry about slashes or anything, all pages are located in the same directory. If I wanted to create a page called "MAE 277 Template" the code would be ''MAE 277 Template'' Note: Brackets are italicized to prevent creating a new page.
Your table of contents is created automatically.
- 1,2,3,4 are level 2 sections
- 1.1, 1.2, 1.3 are level 3 headers
To create headers:
- Section titles are wrapped with two equal signs ==My favorite header==
- Bold headers within a section are wrapped with three equal signs ===My not-so-favorite header===
Asterisks indicate bullets. Be sure to put each asterisk on a new line.
- Here's one
- Here's two *Here's three, but its not on the next line
Bold text:
- Start line with "b" in "<>". Be sure to end the line with "/b" in "<>" if you don't want the whole paragraph to be bold.
- Surround text to be bolded with three " ' " marks on either side. Or highlight the text and click the "B" button on the toolbar.
Italics:
- "i" in "<>". Don't forget to end with "/i" in "<>"
- Highlight the text and click the "I" button in the toolbar (It will put four " ' " on either side).
This is a broken link media file caption
Media tags are indicated by "Media:", images by "Image:" Broken links in red. Case is not important. Use the toolbar to get examples if you're not sure.
Spacing is werid in wiki. Single return does nothing.
Double return (blank line), breaks the line.
Triple return (two blank lines), puts an extra blank line between lines of text.
"br" in "<>" will break lines. They can also be used to separate section headers.
Finally, use the "Show Preview" button on the bottom of the page to see how it looks before saving. It will allow you to catch and edit your errors without having to edit the page again. Just don't forget to save it when you're really done.
