Conclusion
1.      Why is using the vocabulary presented in the tutorials important?
 The vocabulary is important to know for the program because they can help you more easily navigate through the website and use certain commands in the program.

2.      Why is it important to properly select the project each time a model is created?
 It is important to select the project properly because you need to organize the new model under the project that you want it to be a part of.

Activity 4.1g 
1

 1b. I used additive composition for this model because the extensions are easier to make with adding
2

 2b. I used subtraction composition because the niches in the object were easy to create with subtraction
3

 3c. Subtraction was definitely more efficient for this object because the shapes are hard if you use addition, but they are much easier if subtraction is used.
4

 4b. I used addition composition for this model
c. I think that using subtraction composition would have been much easier to do because the shapes are very different in the model.

Conclusion
1.      Why is it important to consider efficiency when planning your method of creation before beginning to model an object in CAD?
 It is important to consider efficiency of a method because you don't want to take too much time. Also, certain deadlines can cause a limit in time.

2.      How can the information provided in the browser of the CAD software help you compare the efficiency of two different methods of modeling the same object?
The CAD modeling can determine how much time it takes or how easy it is to CAD model it versus sketching it.


Activity 4.1 Puzzle Cube Challenge Conclusion
Conclusion
1.    Why is it important to model an idea before making a final prototype?
 It is important to make a model before the prototype because you need to test out the logistics or the product so that it is still possible to repeat the model on a scale of the prototype.


2.    Which assembly constraint(s) did you use to constrain the parts of the puzzle to the assembly such that it did not move? Describe each of the constraint types used and explain the degrees of freedom that are removed when each is applied between two parts. You may wish to create a sketch to help explain your description.
 Using faces that weren't facing the same direction did not constrain together. When one constraint is in place, the other parts of a piece are limited to that of a constraint. So, a total 180 turn connection isn't possible when a constrain connect two points. 

3.    Based on your experiences during the completion of the Puzzle Design Challenge, what is meant when someone says, “I used a design process to solve the problem at hand”? Explain your answer using the work that you completed for this project.
 The design process firstly includes the sketches that one makes to turn a creation into a reality. Before that though is the overall goal, or the design statement one wants to achieve from the project. After the sketches, the modeling and building happens. Then, receiving comments from the puzzle cube testers may be one of the most important aspects of a project. Lastly, recording the results for the average time to solve a cube three times and coming to a conclusion determines the success of the product.



4.    How does the gender of the puzzle solver affect solution time? Be specific and provide evidence to support your answer.
 The nature of a girl is naturally different from that of a guy. Normally, girls tend to be more cautious when handling with thing such as puzzles. In a study by the VK and approved by the Committee for Ethics in Research, Faculty of Arts, and the University of Maribor, researchers found that girls solved different types of puzzles at an average of twenty percent faster than boys did. Observer saw that boys were more likely to fit a piece without being careful about where the piece might fit while girls were more careful in choosing a piece and placing it in a correct position.



5.    How does the age of the puzzle solver affect solution time?
a.    Make a specific statement related to the rate of increase or decrease of solution time with respect to age. Provide evidence that supports your statement.
 The younger you are it becomes harder for you to solve the puzzle. Ex: a 3 year old may not be able to solve it, but a 13 year old would. However, the exception is that people below the age of age 8 will not be able to solve.  However after the age of 25, it becomes harder for you to solve the puzzle.
b.    Write an equation using function notation that represents puzzle solution time in terms of age. Be sure to define your variables and identify units.
                         y= 7x y= time it would take to solve the puzzle x= age 7= average time (in minutes)

c.    Predict the solution time on the first attempt of a child who is 3 years of age.  Show your work.
 21 minutes. However, because it is not in the range of ages this does not apply. 


d.    Predict the solution time on the first attempt of a person who is 95 years of age. Show your work.
 665 minutes

7*95=665

e.    Do these predictions make sense?  Why or why not?
 No, because you can not put a specific function that will meet the puzzle solving skills of all participants.


f.     What is a realistic domain for the function?
 A realistic domain is from 4 year old to around 90 years old

Day 12  Intro to Engineering Allen Sam 6-27-18 Activities 5.5a and 5.5b 5.5a   Conclusion:  1.        What 3D CAD functions could be used to create a wire coat hanger? I would use the sweep, loft, and revolve functions of CAD to create the coat hanger from the front view and a side view. Activity 5.5b \ Conclusion:  1.    What CAD feature would be used to most efficiently model a baseball bat (Extrude, Loft, Revolve, Sweep)? Explain your answer. I would use the revolve tool to create the baseball bat because the baseball bat is cylindrical     2.    How does a 3D CAD solid model program display the progression of work involved in creating a model? You can see progression of the work of a project by showing the constraints and CAD features that were used. 3.    If a mistake is made, how does the user make a correction without using the undo function?
