PROJECT: CO2 Dragster


Problem Statement:
To research, design, construct and report on the results a of CO2 powered dragster to go down a 20-meter track in the least possible time.
Design Criteria:
1. The dragster must have a mass of 30 grams or more.
2. The completed dragster must have a minimum/maximum length of 10”.
3. The completed dragster must have a maximum body width at front and rear wheels of 1 3/8"”.
4. The dragster must have a cartridge hole depth of 2”.
5. The dragster must have a cartridge hole diameter of 3/4”.
6. The height of the cartridge hole from bottom to centerline of the hole must be 1 1/4”.
7. The dragster must have a minimum of 1/8”of wood around the entire cartridge and axle hole .
8. The dragster must have two screw eyes, one toward the front and one toward the back of the centerline, on the bottom of the dragster.
9. The axle hole is 3/8" high from the bottom of the blank
10. The dragster must be made of solid wood of sufficient strength to withstand racing.
11. Bearings, bushings, and lubricants may be used in the construction.
12. The dragster must have four wheels with a maximum diameter of 2 inches.
13. Wheels must be made of plastic.
14. The dragster must have two axles.
15. Axles must go through the body of the dragster. External axle tubes are not permitted.
16. In the opinion of the judge(s), any dragster deemed unsafe will be disqualified... DQ and i don't mean Dairy Queen!
17. extra wooden body blanks may be available to replace your errors at your COST!
Competition:
1. Dragsters will run two at a time.
2. Dragster will run on a fishing line down a 20-meter track.
3. Race will begin when firing mechanism is fired. Both dragsters will start simultaneously.
4. Race will end when the dragster passes at the finish line.
5. Winner will be determined through single elimination.
