Chapter 1: The History of Engineering
"If
I have seen further than others, it is by standing
upon the shoulders of giants."
- Isaac Newton
Why learn the history? New innovations stand on the shoulders of
those who have gone before.
The speed at which things now change indicate
the urgency of understanding the process of innovation.
Just for fun:
Students heading into their first year of college this year...
http://www.beloit.edu/mindset/.
We live in the information age.
Change is expected.
New generations do not do things the way older generations did.
Now:
Make a house frame in a single day
Then:
200 years to build a church.

Discussion question:
Why were there so few innovations in the early
years?
We have progressed more in the last 200 years, than in the previous 5,000+ years....
For thousands of years, people farmed with crude manual labor, lived their whole life within a small radius, battles were fought with spears and arrows - technology was stagnant for thousands of years...

Moral of the story?
It's important to learn how to write, present, and otherwise share information. Information is key to engineering.
Prehistoric Culture:
- No math or science
- No written language
- Limited verbal language
- Limited means of transportation
- They didn't go to school
- Spent most of life as hunter / gatherer
- Built using trial and error
- Used intuition
- Craftsmen
Lesson of Prehistoric Man: You can make things without understanding the science behind why it works.... but the more you understand, the better your product will be.
Discussion Question:
Are we better off?
Archimedes refused to release information that could be used to make more effective weapons; he knew it would be used for evil... only when his home city was no longer able to hold off Roman attacks did he release his inventions to the military.

Stone Age -
ended between 4500 BC and 2000 BC with the advent of metalworking.
Bronze Age -
The use of copper and it's alloy bronze (Copper + Tin)
Copper melts at 1,085°C
Tin - melts at 231.9°C
Iron Age -
Iron melts at 1,538°C
Harder
to melt - harder to make, plus you have to worry about impurities
introduced in the heating process. (Impurities generally make iron
brittle and worthless)
The
stronger the material a society had, the more it could build, the more
powerful the military (long swords vs. short swords) the more powerful
the society.
Engineering is dependent on the strength of the materials it has to work with.

What will you see in your lifetime?
Where do you fit in with all of this?It is estimated that to produce just one pound (0.45 kg) of honey, the average hive of 20,000 to 60,000 bees must collectively visit millions of flowers and travel the equivalent of two times around the world. Over its short lifetime of just a few weeks to four months, a single honeybee’s contribution of honey to its hive is a mere one-twelfth of one teaspoon.

(1) ** Study these diagrams, watch instructional youtube videos, and be prepared to explain the operation during the class presentation.
Section 2: Production of internal engine.
Raw materials.
Mark Wan from the AutoZon Technical school reports that most engines are now made out of lightweight Aluminum that is coated with either cast iron or Nickel-silicon carbide to reduce friction between the parts.(2) The materials that combustion engines are made from has changed from cast iron to Aluminum alloys in order to reduce the weight of the engine and produce higher energy efficiency.
Process.
The engine block is created by “sand casting” or melting the desired aluminum alloy, and then pouring the molten metal into a sand mold. After the metal hardens, the sand is removed, and the engine block is machined into it’s final form. (3)
The pistons, crankshaft, and other rods are created through a forging and forming process where metal is heated and forced through a die. The forging process increases the strength of the metal by introducing atomic packing defects which prevent slip planes from propagating in the microstructure of the metal. (4, 5)

Use Lists
Lists are often the most efficient way to communicate information.
List material from most important to least important
3 types of lists:
Directness:
Avoid suspense.
Put the most important information first.
example: Indirect: After a long and difficult development cycle due to factory renovation, the infrared controller will be ready for production in the very near future.
Direct: The infrared controller will be ready for production March 4. Its development cycle was slowed by the factory renovation.
Avoid wordiness
Avoid unnecessarily pompous or ostentatious & showy words. The point of technical documents is to convey information, not to make yourself look smart.
keep it simple and straightforward.
Remember, often your readers have English as their second language.
pompous - straightforward
Turning verbs into nouns:
Write in an active voice (rather than passive) by using verbs instead of nouns.
wordy – clear
Report
References
Should be numbered at the end of the report, and referred to in the text by their number.
Presentation Checklist:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Make sure you know how to format a technical paper before your next report!
Learn how to add numbered footnotes - (google it if you don't know how)

- Why you are writing.
- Why you are writing.
- to inform, request, instruct, propose, recommend, persuade, record?
- Who are your readers?
- Fellow engineers from your field?
- Engineers from a different field?
- Managers? Marketing?
- Mixed audience?
Are you communicating technical information on a level your audience can use?
Are you using appropriate vocabulary, examples, definitions, and depth of detail?
Satisfy Document Specifications
Satisfy Document Specifications
- Adhere to suggested length.
- Format spec’s: headings, spacing, margin widths, font
- Format spec’s: headings, spacing, margin widths, font
Get to the Point
- Put important info first.
- Intro - briefly state key points, complaints, requests, and conclusions.
- Do not include details until the body of the text.
Accuracy
- Accurate references
- Accurate directions and instructions
- clearly state the conditions your data is applicable to.
- Do not state opinions as facts.
Logical Presentation and organization:
- Numbered sections and subsections with titles.
- Organize in levels of detail and importance
- main subject first
- fill in the details later
- First level headings should be in large font
- separate headings from text by one line
- indent minor headings
Use Lists
Lists are often the most efficient way to communicate information.
List material from most important to least important
3 types of lists:
- numbered (or lettered) for procedures, or prioritized lists
- checklists – for things you need to do
- bullet lists – items in list occur in no specific order
Be Clear & to the point:
Ambiguity – comes from the Latin word meaning to be undecided, causes readers to see more than one meaning in your writing without knowing which is correct.
Avoid words like “they” and “it” to be specific and avoid ambiguity.
Ex:
Ambiguous: Before accepting materials from the new subcontractors, we should make sure they meet our requirements.
Who are “they”? the materials? Or the contractors? or both?
Clear: We should make sure the materials from the new subcontractors meet our requirements before we accept them.
Ambiguous: The microprocessor interfaced directly with the 7055 RAM chip. It runs at 5 MHz. (What does “it” refer to?)
Clear: The microprocessor interfaced directly with the 7055 RAM chip. The 7055 runs at 5 MHz.
Vague – contains no useful information.
Example:
“Take a few of these pills every so often.” How many pills? How often?
Vague: The Robotics group is several weeks behind schedule.
Useful: The Robotics group is six weeks behind schedule.
Vague: The CF553 runs faster than the RG562 but is much more expensive.
Avoid words like “they” and “it” to be specific and avoid ambiguity.

Use a clear subject for each paragraph
Everything should support the subject of report
Directness:
Avoid suspense.
Put the most important information first.
example: Indirect: After a long and difficult development cycle due to factory renovation, the infrared controller will be ready for production in the very near future.
Direct: The infrared controller will be ready for production March 4. Its development cycle was slowed by the factory renovation.
Avoid wordiness
Avoid unnecessarily pompous or ostentatious & showy words. The point of technical documents is to convey information, not to make yourself look smart.
keep it simple and straightforward.
Remember, often your readers have English as their second language.
pompous - straightforward
Commence – start
Compel – force
Comprises – is
Employ – use
Endeavor – try
Fabricate – make
Finalize – end
Initiate – begin
Optimal – best
Prioritize – rank
Proceed – go
Wordy: I regret to say that at this point in time I basically do not have access to that specific information…
Clear: “I don’t know.”
Wordy – efficient
A large number of – many
At this point in time – now
Come in contact with – contact
Exhibits the ability to – can
In the event of – if
In some cases – sometimes
In the majority of instances – usually
Redundancy
using multiple words to say the same thing
Redundant – clear
using multiple words to say the same thing
Redundant – clear
Alternative choices – alternatives

Paragraph Length:
Avoid walls of words
rule of thumb – keep paragraphs to under 12 lines
Most paragraphs will be much shorter. (one liners are just fine)
Formatting

Formatting
Margins – Use large margins to prevent pages looking too busy
Typeface – 10 to 12 point, Times New Roman, Arial
Use ample “white Space” around figures, headings, paragraphs, equations, & lists
Manage your time
Create and use a schedule
Give yourself time to edit
Team: divide and conquer, assign different sections to different people, but then have one person organize, and re-write it to create a smoothly flowing document (rather than a patchwork quilt of different writing styles)
Graphics & Charts –
use numbered figure captions,
refer to the figure in the text by the number.

Tables
include a table heading. Heading go above tables (figure captions go below figures)
include a table heading. Heading go above tables (figure captions go below figures)
References
Should be numbered at the end of the report, and referred to in the text by their number.
Presentation Checklist:
Make sure you know how to format a technical paper before your next report!
Learn how to add numbered footnotes - (google it if you don't know how)
- Use Headings - bold, numbered, underlined
- Use bullet lists and numbered procedures instead of long paragraphs.

- If different people write different sections, make sure when you put it all together it looks like one single report written by one single person.
- Don't plagiarize!
- Warning - I do random google checks on what you have written. Cite your references, use small quotes if you need to, but most of the report should be in your own words.
- Pay attention to simple grammar and spelling!
Eye halve a spelling chequer
It came with my pea sea
It plainly marques four my revue
Miss steaks eye kin knot sea.
It came with my pea sea
It plainly marques four my revue
Miss steaks eye kin knot sea.
- Read what you have written out loud
- if it sounds strange when you hear it, then fix it.
- Read through the work of your team.
- Pay them $0.25 for every mistake they find in your work.
- Presentations
- Practice with one another
- practice in an empty room
- videotape yourself, watch yourself, and fix what you see.
Pay attention to people who impress you, - copy their techniques.
Use the LSC writing center!!

Misc:
- Create a cool bike rack that promotes community exercise.
- Refurbish old bicycles for disadvantaged children.
- Make a local park more handicapped accessible
- Design a toy or activity that promotes science, technology, engineering, and math at a local school.
- Come up with a plan to improve the parking at LSC.
- Find a cure for cancer... :)
If you choose to do a Civic Engagement project, you can submit your project proposal to LSC's Center for Civic Engagement.
