3.1.6

1. build support system

2. Add motor and gear box


support system and motor

5. is this an open or close loop system
  • it is a closed system
6. Where do you think the gear box would have come to rest had you set the program to cycle 120 times
  • it will stop on the same place you started
7. What problems and indecencies might this process cause if used in an assembly mechanism designed to run 24 hours a day 7 days a week
  • it would wear out the small motor
switch design

9. is this an open or closed loop system
  • closed
10. how prices would this device be if it were designed to cycle 500 times
  • it would be very precise
this is the program to run the mechanism back and forth 20 times



Conclusion

1. Describe an open loop system that has not already been given as an example
  • gas tank  

2. describe a closed loop system that ha not already been given as a example
  • elevator that we are making in class

Money Ball

1) What was the “Moneyball”approach that Billy Beane and Peter Brandt applied to the Oakland Athletics 2002 season? Was it an “art” or a “science”? What single statistic did they boil their value consideration down to? (In class research/discussion)
  • science
  • boiled down to on base precentiage

    2) What is the equation used to calculate OBP? (In class research/discussion)



OBP = \frac{H+BB+HBP}{AB+BB+HBP+SF}
 formuls used to calculate on base precentage


3) What is design? (In class research/discussion)
  • it as the blend of art and sience




4) Describe 3 situations where movie characters (intentionally or not) applied a step from the PLTW 12 Step Design Process. Explain both the (a) situation as well as (b) how the step is relevant:
1 -step 1 define the problem
  • when billy bean talks to the scouts about them knowing what the problem is

2 - the prototype whith the a A's experimenting with mone ball allowing the red soxs to use the money ball aproch



5) What is “Leadership”? List the three aspects of leadership that we come up with in class. (In class research/discussion)

1 - direction
2 -aliment
3 -commitment


6) Describe 3 circumstances from the story where a character exercised effective leadership:
1 -the firering of jieombie

2 - when billy bean  moves from the traditional approich to the money ball aproch

3 - peter shows effective leadership when he talks with the players



7) According to the movie, what was the A’s record at the start of their winning streak? _76__ : __51_8) What does this ratio simplify to (roughly)? __4_ :   5 9) How long was the A’s record setting winning streak? __20_ games won.

10) Given the A’s win/loss ratio at the start of the streak (listed two questions above), what are the odds of winning 20 games in a row? Run the numbers. (In class research/discussion)

.000037

11) Based on your calculation, do you think the A’s got lucky or was there something to the Moneyball approach?
  • the buying of players that got on base was a key thing in there 20 game win streak
12) Did Billy Beane strictly apply the “science” of Moneyball to his management approach? Was there an “art” to his efforts as well? Describe a circumstance where he broke from the Moneyball approach to make a positive change for the team.

  • he aplied the money ball approch to his life as well when he turned down the red soxs offer

  • he broke of the money ball aproch when he fired geombi which was one of his money ball pickes because he was a bad influnce ofn the team.

activity 3.1.2 folw chart

Flow charts

triangle:
  • represents 
oval:
  • represents start and finish
diamond:
  • represents decision making
Boxes:
  • represents order's
Arrows
  • represent direction
 here are my wo flow charts


 


flow chart No.1  represents the order of weighing an object and determining where it goes

engineering ground zero

1)What different "trades" (types of construction work) are featured in this video? Name at least three.
  • construction workers
  • engineers
  • designers
  • carpenters
  • cement workers
  • steel companies 2
  • glass company
  • electricains



2)What aspect of the project is most interesting to you? Why is that?

the aspect that was most interesting to me was the designing of the tower and the monument.  designing the monument to look beautiful and yet in a void.  with the tower trying to make it look beautiful and to be safe with concrete blast walls and then adding slots to make lights come in to make the tower glow.

deep dive

1. “From the buildings in which we live and work, to the cars we drive, or the knives and forks with which we eat, everything we use was designed to create some sort of marriage between ____form_____________ and ____function_____________.”



2. The folks at IDEO state that they are not experts in any given area. But, they do claim to be experts on the _________process of how you design things ___________, which they apply to the innovation of consumer products.



3. After the team of designers is brought together, told the problem, and informed they have five days to “pull it off,” what phase of the design process do they immediately engage in?

Brain storm and good ideas






4. Give two examples of what the team members did during this phase.

a. Team work


b. Brainstorm





5. List five rules-of-thumb that IDEO employees follow when they share ideas during the brainstorming phase:

a. One conversation at a time


b. defer judgment


c. No criticism


d. Building on others ideas


e. Stay on topic





6. Why should wild (and sometimes crazy) ideas be entertained during the brainstorming phase?

because they could come up with that one great idea or they could build on other team members ideas 








7. After the brainstorming phase was over, the team narrowed down the hundreds of ideas by ___voting__________ for those ideas that were not only “cool” but also _____build able____________ in a short period of time. What phase of the design process is this called?

Enlighten  Trial and Error



8. IDEO believes that the ideas and efforts of a ____Team__________ will always be more successful than the planning of a lone genius.



9. Once the ideas were narrowed down and divided into categories, the group was split into four smaller teams. What phase(s) of the design process was each of these groups responsible for?

  • Shopping
  • Safety
  • Check out
  • Finding stuff you need



10. The leaders at IDEO believe that ______Playful______ behavior and a _Fun        environment are two important reasons why their employees are able to think quickly and creatively to produce innovative results.



11. Sometimes, people come up with great solutions that work by trying their ideas first, and asking for _____Opinion____________ later.


12. Design is often a process of going too far and having to take a few steps back. What phase of the design process would the critique of the four mock-ups come under?

refinding and communicating there results
13. Upon critique of the four teams’ models, it was obvious that none of the teams had developed an optimum solution. However, the people at IDEO believe that it is important to fail often in order to _____succeed________ sooner.



14. What percentage of the entire week’s time did it take to fabricate the final prototype?
 20% one day




15. Instead of showering his design team with a tremendous amount of praise, what did the boss require his employees to do with their new design?

Improve on there design



16. Of all the things that we are surrounded by every day, what has not been placed through the design process?
  • Human Body
  • Nature
Conclusion

1. What did you find to be the most impressive part of the team’s effort?

  • There commitment to the team
  • there commitment to the project
  • there overall final product






2. What advantages are there to having a design team with members that have non-engineering backgrounds?

  • Crazier ideas
  • better enviorment





3. There was a point in the process where a self-appointed group of adults stepped up, stopped the ideas, and redirected the group to break up into teams. Why was this done?

to set the team back on course if they hadn't the team wouldn't meet the deadline or they would have rushed the project and done something wrong




4. At the end of the video, Dave Kelly states, “Look around. The only things that are not designed are the things we find in nature.” Can you think of anything that would contradict this statement?
