Fling Machine Reflection

Data Recorded: 15', 18', 20', 20', 22', 16', 18', 19', 21'

It is pretty well distributed with 18, 19, 20 feet in the middle.

Mean: 18.8'

Median: 19'

Range: 7

Sample Standard Deviation: 2.1499

I predict that most of the cotton balls will launch between 18-20 ft based on the data we received from the tests we tried.

It won't be improved with the performance of alternate device comparison because the original data will still be the same.

I actually prefer giving points for distance traveled since we were 2nd farthest, but if I was to recommend, I would recommend finding the average of the test launches for points, and originality.

I would have made our plane more dense and smaller, and made it easier to fly. I thought throwing the entire device all together was bending the rules too much.

We only used aluminum foil and cotton balls, so the only reduction would be in size.

To improve our team, I could try to use some of my partner's idea if they were any good.

Unit Conversions

In this project, we made a presentation about accuracy and precision, US and SI units, Dimensional Analysis, Significant Figures, and Rules of Exponents. The link to the presentation is here. We accidentally skipped the slide which showed accuracy and precision.

From this project, all the unit conversions seemed to be a little more exciting, but it is still going to be boring as ever, because it is long and no fun.

Color Theory

A color scheme is an arrangement or combination of colors, especially as used in interior decoration. The different kinds of color schemes are monochromatic colors which creates a soothing effect which makes an overall mood, analogous colors which uses a color as a dominant color and adjacent colors to surround it, complementary colors which have opposite colors on the color wheel put next to each other, and split complementary is a variation of complementary colors two adjacent colors are matched against its opposite color. A color triad is any combination of three colors on the color wheel.

The three primary colors are red, blue, and yellow.

The three secondary colors are violet, orange, and green.

The six tertiary colors are blue green, blue violet, red violet, red orange, yellow orange, and yellow green.

Examples of Color Schemes:

Monochromatic color: 

Analogous color: 

Complementary color: 

Triadic Colors: 

Split complementary color:

Multi-View Sketching

this was my multi view sketch of one of the objects.

This is Paras intensely studying the cube with multi view sketches on it.

this was all the work inside my notebook.

The purpose of construction lines is to keep the shapes in a 1:1 ratio and help form the different views. 

Hidden lines and center lines shows the parts of the shape that can't be described in the view. 

The first picture seemed more like a front view because it showed most of the lines of the object.

The 6th picture seemed more like a side view because the object's longest side was shown and doesn't have the most lines.

Multi-view drawings are used by professionals because it describes all sides of the object, unlike pictorial drawings which only shows one side. Not to mention, multi-view drawings are all in a 1:1 ratio to eachother. 

Design Concept Presentation

This is the omni-wheel I presented in the presentation

This is the model of a shopping cart I built using masking tape and copper wires.

Interview With a Designer

When we first met Josh, he seems like a pretty relaxed guy. I was rather surprised, because I was kind of expecting him to be more . . . formal, i guess. I was really glad that his old workplace as a designer was a place to mess around and people rolling around on skateboards. When I heard that designers can make $40-80, I was extremely shocked. However, what surprised me the most, was that he didn't actually go to college and still got a really nice job. 15 minutes with him went by rather fast, but we also ran out of questions to ask him. I think a chance with a designer who works with physical objects  or someone who prototypes ideas would further improve our knowledge of designing.

Revised Concept Sketches

The shopping cart will have torsion bar suspensions as a change, along with rounded edges at every corner on the shopping cart. The sides will still be PVC, but it will be a full sheet of PVC. The bars will not be foldable.
