Egg Drop Challege

For the egg drop challenge, where we had to drop an egg as slow or fast as possible without it breaking, my group decided to cushion the egg in cotton and at first we wanted to place it in a box but later switched to just a cup for aesthetics and a lighter weight and less bulkier body for better aerodynamics. We also put baby power in the parachute so it oped better.

Prep: We sketched it out on a a whiter board and discussed ideas & goals. We then began making it and we accurately matched the weight of an actual egg during our testing by filling an easter egg with marbles and getting it to the average egg weight using a scale.

Materials:
 Box (then didnt)
Cotton
String
Tape
Egg
Plastic Bags
Cups

Achievements:

• Sketch One possible solution

• Sketch Second possible solution

• Sketch Third possible solution

• Use Decision Matrix to justify which solution to use

2.1.5 CAD Model Features Conclusion

Conclusion 1. What 3-D CAD functions could be used to create a wire coat hanger? The ribbed function. 2. What feature would be used to create a 3-D representation of a spindle that was created on a wood lathe? The cylinder function. 3. How does a 3-D CAD solid model program keep track of the changes that are made to an object? By saving it to a temporary database. 4. If a mistake is made, how does the user make a correction without using the undo function? By deleting the area of the mistake and redoing that area.

TED

1) What is the TED organization about?
Spreading and later sparking ideas & causing positive change through the ideas.

2) What is the purpose of their website and how does the functionality of their site support that?
The purpose of their website is to spread ideas and the functionality of their site supports that by having various tabs of video organization, ability to watch on website, and various ways to save and share them.

3) As Engineers and Problem Solvers, which topic areas (the choices from the "Show talks related to:" section on the sidebar) are of most interest to us? Justify your answer. 
They all are of interest to us because they all present problems for us to solve or new ideas or information for us to learn and apply through engineering.

4) Based on your previous answer, what are 3 talks (videos) on the site that appear like they would be of most interest to you as an Engineer/Problem Solver? Justify your choices. 
For me personally as an engineer/problem solver, the 3 videos that would be of most interest to me would be Bill & Melinda Gates on Why Giving Away Their Wealth Was The Most Satisfying Thing They Ever Did because I feel there is a lot of greed and not enough use of money for others and Kakenya Ntaiya: A Girl Who Demanded School because I feel women equality and women education especially is very important & Coding a Better Government because its a way to solve the problem of government being to closed off.

1. What is a geometric constraint?
A geometric constraint is a constraint on the shape of the object.

2. What are the different types of geometric constraints that are applied to sketches, and what are their functions?

Coincident; make the item go through a certain point.
Collinear; makes the items ly on the same line.
Concentric; makes the items have the same starting point.
Fix; makes items relative to coordinate points.
Parallel; make the items match but not on top of each other,
Perpendicular; make the items cross each other.
Horizontal; make the items horizontal.
Vertical; make the items vertical.
Tangent; makes curves match other curves.
Smooth; smoothes out bumpy curves
Symmetric; making the items match.
Equal; makes the same item.

3. How is a geometric constraint different from a numeric constraint?
A geometric constraint changes the shape while a numeric constraint changes dimensions.

4. What types of numeric constraints may be applied to sketches?
Numeric constraints that may be applied to sketches are length, height, width,spacing, & radius.

5. What advantages do CAD sketches have over freehand sketches?
CAD sketches have the advantages of preciseness over freehand sketches.

6. What disadvantages do CAD sketches have over freehand sketches?
Disadvantages CAD sketches have over freehand sketches is that it is a lot harder and easier to make a mistake because of the overall complexity.

Tennis Ball Design-build Challenge prt2

This time we revisted the original tennis ball design build challenege but this time we had $12,000 (fake) to purchase classroom items and get across only a 2ft gap.

This time we used cardboard again but with a more slide like design (curved bottom), more supplies, and a larger slope we made one that worked.

Tennis Ball Challenge prt1

Design-build Challenge: Using only $10,000 (fake money) to purchase various classroom supplies, you had to building a bridge across a gap of 3ft and get a tennis ball to roll across the bridge.

We used taped and cut manilla folders to try and get it across but unfortuanetly ours did not work.

Super Bowl Ad (Fav. Ad & Widgets Sold Needed)

For our superbowl commercial project, we had to pick our favorite commercial from the superbowl, tell why we picked it ,tell how much it approximately costed them, and then tell how many widgets they had to sell to pay back the cost of it.

 I picked the Duracell batteries commercial because it was very motivating and inspiring that a deaf football player who didn't even make the NFL draft ended up playing on the superbowl winning team.

The advertisement is 1.01 minutes so that costs around 8M(based on 2013 30 sec. equaling 4M on average) plus the commercial making costs is probably .5M so the total is approximately somewhere around 8.5M which means Duracell needs to sell about 1,625,240 batteries (based on average Duracell battery cost of $5.23).

Puzzle Cube Project

 Make sketches of all possibilities of 3 cubes, 4 cubes, 5 cubes, & 6 cubes no higher or longer than 3 x 3.

Make 2 possible cubes and test which one is harder.

Build the puzzle cube.

Choose 1 out of the 2 possible puzzle cubes you designed and make step by step instructions.

Build packaging for the cube & place the puzzle cube inside it.

Now make a blog post for the whole project.

What we learn: 

How to be creative within constraints. 

How to work within a deadline

Cardboard Canoe Challenge Recap

I am claiming 9  achievements.

Design Achievements 

X• Define the Problem and Brainstorm Solutions -

Sinking : Keep whole thing ductaped 

add extra support.

add flotation device design

X• Criteria & Constraints - List or reference the specified Criteria and Constraints you're designing for.
A boat to float across a pool.

XList at least one implied criteria. List at least three implied contraints.
1.Floating

1. time
2. materials
3. partners

• Sketch Ideas - Draw 3 different sketches for possible designs. Label at least 3 key features for each sketch. Describe the feature's functionality so a viewer understands why the called out feature is important.

• Prototype Ideas - Craft physical prototypes (models) of each of your three sketches. Use a note card or post it note to call out at least one key feature on each model. Post the images to your blog and describe the key feature that you've pointed out on each.

X• Select an Approach - Generate feedback (+, change, ?, !) and make a decision matrix regarding your sketches/prototypes. Specify the approach you've chosen and justify your selection.
Specification & Justification: I have chosen the approach to treat the cardboard canoe as a stock-racing car and make it as light & aerodynamic as possible.

X• Surface area! - Calculate how much surface area you can cover with your given duct tape. How many sf can you cover with one roll? How many can you cover with all your rolls? What % efficiency do you think you can achieve with your overlap?

s=surface area
d= ducttape
a= amount of rolls

d * a = s
1.89in X60.1yd)=
618.408in = 1 role
618.408in X 4rolls =
2473.632in. (68.712 yd.)
I think I could have achieved 50% efficiency with the overlapping.


Build Achievements:

Test Achievements:
X• Balance Master -Zola "surfed" the canoe.

X• Videographer - Take video of the challenge and post to your blog.

X• How Low Did You Go? - How low in the water did your canoe sit (roughly)? Was it surprising how little your boat went down in the water? What is the unit weight of water in pounds? How much did your pilot weigh (roughly)? Use math to help explain the depth that your boat sat in the water:

Our canoe sat roughly 3 in. in the water. It was very surprising how little our boat went in the water.

It is converted from 3 in. of water to 0.11 p.s.i.(per square inch). Wyatt Zola our pilot weighs 95 lbs.

X• (Make Your Own Achievement) - Make an achievement of your own design that you can award yourself for something awesome your team did. (Example "Transformer" - although our canoe sunk, our team was able to convert it into a surfboard style design and continue competing!):
"The SUPER Digital Media Achievement" for getting multiple members of our canoe's crew to capture the event in digital media.

Reflection Achievements:
• Feedback - Generate ten items of feedback for your effort (from the design/build process and/or the actual product). Make sure you include at least one item of feedback in each of our four feedback areas (+, change, ?, !)

• Redesign - If we were to do another Cardboard Canoe race next semester, what would you build? Draw from everything you experienced in your class and propose the most competitive solution. Include a sketch with key features and dimensions labeled:

My First Blog Post

Greeting random blooger-surfer! Welcome to my school blog for my Intro to Engineering class.

I like innovating/designing. I create t-shirts, websites, plan out the gov. bills to pass when I become a powerful role in our gov., design housing structures, designing cars, etc.

Here is a link to a website that I designed to sell clothes that I designed: http://www.highlifeclothingco.com/
