PROJECTS
Project 1: Heat Treatment
Assignment Date: October 14th
Selected Presentation Date: November 3rd, during class time
Submission Date: Full report on November 3rd, before class time.
Take a look at the Heat Treatment Experiment video at the this link. Review your materials from IEGR 309 class to refresh yourself on terminology. Review heat treatment chapter of your textbook for proper explanations.
Warning: This experiment involves heating objects to high temperatures but nothing beyound what you do to cook your food. Use all safety precausions necessary to avoid burns and injury. If you feel that you are not capable of safely performing the experiment, you need to inform the instructor at least one week before the due date to receive an alternate assignment.
What you need: Few bobby pins (alternatively you can use paper clips), a source of heat such as a gas burning stove inside your kitchen or a charcoal grill ouside. You also need pliers to hold the bobby pins when they are being heated, safety golves and glasses, plus four small empty cans (like tomato sauce cans). Finally, some salt, oil (like engine oil or cooking oil, clean or used) and sand are required .
1. Fill empty cans, tap water in Can 1, tap water plus two spoonful of salt (stir to dissolve the salt) in Can 2, oil in Can 3, and sand in Can 4.
2. Hold a bobby pin with pliers (similar to the video) and heat it. When red hot immediately insert it in Can 1 to cool down. Place it aside and
make note of which can number it was cooled in.
3. Repeat step 2 for Cans 2 and 3 using different pins.
4. Heat Can 4 (containing sand). Repeat heating a new bobby pin till red hot and insert it in Can 4. stop heating Can 4 and let it cool in room temperature.
Then remove the pin and set it aside.
5. Repeat similar experiment, except this time hold the pin in the pliers in room temperature to cool down. Set it aside.
6. Since, you do not have any equipemnt to measure the exact differences, your measurements will be qualitative based on your own impression. Create a table
and for each pin related to the experiment rate from 1 to 10 how much force is needed to open the pin to about 30 degrees. Use rating of 5 for an unheated pin.
Note that 1 refers to easiest one to open and 10 to the most difficult one. Note that some of the pins might break before they are opened to 30 degrees.
You just need to record the force that you felt required when trying to open those pins.
7. Again repeat the expermint by heating a new pin and cooling it in Can 1. Hold the cooled (and dried) pin above the heat source (check the video)
and again gently heat it until it is hot but not red hot. Hold it away from the heat and let it cool down in the the room temperature. Again, try to open the
pin to 30 degrees and note any difference you feel with the pin cooled in the same can from previous experiment.
Document the entire experiment including images in your report. Discuss what each experiment represent and what the impact of those heat treatment processes are and why they have such impacts. A full report is expected for this project.

Project 5: Product Design
Assignment Date: October 14th
Selected Presentation Date: October 20th, during class time
Submission Date: October 20th, before class time.
Take a look at the Wooden Sling Hockey Board Game design at the this link. Using the materials that you can find at home or buy from the stores, design, build and demonstrate your final product.
Document your building processes in a PowerPoint presentation including all measurements, bill of materials and process plan.
Your documentation should also include a short video demonstrating how it works. You need to make sure that you assemble your project
from raw materials and not ready made ones. For example you cannot use ready made pugs, you need to make them yourself.
Use materials that you are comfortable working with, metal, wood, cardboards, etc. List all the toold you used in your project.
Keep the size comparable to the actual product (around 36 Cm).
