ENGR1201: Group Homework assignment #1:
Engineering Product Paper & Presentation.
Due: Jan 21, 2014

For this group assignment, choose an interesting product that was created by an engineer. Your group will turn in a report (one or two pages per section) and give a short (10 minute) class presentation on the product that you choose. Each group member should be responsible for preparing and presenting at least one section of the report. The product chosen should be sufficiently complex that it requires advanced engineering skills to build it (in other words, don’t choose something as simple as “a table” to do your report on), but specific enough that a general understanding is possible in a short report (ie, instead of choosing something like an entire airplane, choose only one part of the airplane, like a jet engine, to do your report on.) Use your own words, and reference the internet sites (or books) that you get your information from.

Heading: should include class name, date, project title, and the names of all the group members.

Section 1: (10 points)
Find, and print out a diagram of this product using the image search tools on google. Briefly explain what it is, what it does, and how it operates.

Section 2: (10 points)
Explain the process used to make this product including what company makes it, what raw materials were used, how they were formed, and how different parts of the product were assembled.

Section 3: (10 points)
Discuss different models of this product, and how the design has evolved through time.

Section 4: (10 points)
Make a list of several different engineering disciplines that were involved in making the product, and explain what each type of engineer contributed. Include a short biography on one prominent engineer who significantly contributed to the existence of your chosen product.

Presentation: (40 points)
Print out one or two pages per section that summarize your findings. You may use the class document camera, but you should not just read straight from your slide.

Watch the TED talk by Amy Cuddy: Your body language shapes who you are on youtube.
Incorporate what you learn from Amy’s talk into your presentations.

Keep it brief! 2 minutes per section, skip the details, and present only the general idea of the thing. Be prepared to answer a few simple questions as a group at the end of your presentation.

Format: (20 points)
See notes on http://engr1201.blogspot.com/2013/12/writing-as-engineer.htmlon how to write a technical document. Your report should have headings, subheadings, organized lists, and references.

Example Product: 4-stroke internal combustion engine.

Section 1:. Diagrams of a 4-stroke internal combustion engine:
Engine Block:


(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)

Assembly:
Parts are assembled through a combination of machines and manual labor. (6)

Example companies that produce combustion engines:
GM, Ford – United States
VW, BMW – Germany
Toyota, Nissan, Honda – Japan
Hyundai – South Korea

Section 3: Brief history of the internal combustion engine.Read through resources such as this:
http://en.wikipedia.org/wiki/History_of_the_internal_combustion_engine
Choose and highlight what you believe to be the most important developments of your product.

Section 4: Engineering Disciplines needed in creating an internal combustion engine:
- Chemical Engineer – Refines the fuel used in the engine.
- Mining Engineer – blasts away rocks to reveal ore veins, and mine the raw materials for the parts.
Metallurgical and Materials Engineer – Creates the best material (lightweight, strong, corrosion resistant, performs under high-temperatures and pressures, cost effective) from the ore produced by the mining engineer.
- Mechanical Engineer – Designs engine using applied mechanics and thermodynamics calculations.

Give a short biography of one of the original engineers who first created or significantly improved the product.

*** check out the "How It's Made" youtube videos - these are a great reference! Just do a youtube search with "How it is made ____________" fill in the blank with your product. Wiki is fine, materials from other schools are fine, materials from companies are fine - use a variety of different reference sources in your report.
