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).
