1. CO 2 Dragster Design Limitations

2. Limitations of the CO 2 Dragster

3. 7. Dragster Body (Length) 12” (max.) 7-7/8” (min.) 8. Dragster Body (height @ rear w/ wheel) 2-15/16” (max.) 2-3/16” (min.)

4. Limitations of the CO 2 Dragster #10 #10. Width of Dragster at the Axel Points (Front & Back) 1-1/4” MIN 1-1/2” MAX

5. Limitations of the CO 2 Dragster 11. Power Plant (depth of hole) 2” MIN 2” MAX. 2” 12. Power Plant Thickness 1/8” MIN

6. Limitations of the CO 2 Dragster Power Plant Center from the bottom of the body 1-1/4” MIN 1-1/4” MAX #13

7. Limitations of the CO 2 Dragster #14. 14. Eyelet Screw Placement (Distance Apart) 6-1/8” MIN 10-5/8” MAX

8. Limitations of the CO 2 Dragster 15. Wheelbase 4-1/8” MIN 10-5/8” MAX #15.

9. What makes for a fast CO 2 Dragster?  Weight – The lighter the CO 2 Dragster the faster it will go.  Friction points  Eyelet screw placement  Wheel setting  Aerodynamics

10. Gather Information  Designing and producing a CO 2 Dragster  Speed (the faster the CO 2 Dragster is the more points you receive)  Finishing (Two or more colors)  Durability (CO 2 Dragster must stay intact for two races)  Limitations (You must design your CO 2 Dragster around the parameters on Page 5 of the packet

11. Defining Your Design Problems  Recognize and define the Problem – When defining the problem, consider the boundaries, the parameters, and the limitations. A very narrow, well defined, specific problem will be easier to solve than a board, all encompassing generation. Think about what has been discussed in class including the limitations of the dragster. In the space provided below write a definition for the design problem presented to you.  Requirement: You must write a short statement (in full sentences) that best defines your tasks.

12. Definitions In complete sentences, write a paragraph that address these 5 considerations. (3 – 5 sentences)  Designing and producing a CO 2 Dragster  Speed (the faster the CO 2 Dragster is the more points you receive)  Finishing (Two or more colors)  Durability (CO 2 Dragster must stay intact for two races)  Limitations (You must design your CO 2 Dragster around the parameters on Page 5 of the packet.

13. Consider Possible Solutions  To accomplish this step  Gather as much data and information as possible.  Use brainstorming techniques to come up with ideas.  At this point anything goes – be creative – be resourceful  Requirement:  You must sketch 8 different ideas as possible solutions in solving your task.

14. When Designing Don’t forget to K.I.S.S.  K KEEP  I IT  S SIMPLE  S STUDENTS

18. Use brainstorming techniques  Complete 8 thumbnail sketches to explore different possibilities to solving this design problem.  Thumbnail sketches are quick sketches and does not require you to consider the limitations  Think out side the “box”  Be creative
