Building the Fastest CO2 Car for School Project

In summary, The conversation is about making CO2 cars for a school project. The person is looking for the best design to make the fastest car, with the specifications of a maximum body length of 12 inches and a minimum of 7 7/8 inches. The cars will be raced on a 75' track. The person is wondering about ways to optimize the car's speed and the variables that affect its acceleration and top speed. They also ask if it's possible to upload CAD pictures to the forum.

ok for school, i am having to make CO2 cars...here is some information about it

http://en.wikipedia.org/wiki/CO2_Dragster

well anyway, i need to make the fastest one...(kinda of to help my grade xD) well i was wondering what the best design is for it...

the specifications i must have for body legnth are...
Maximum: 12"
Minimum: 7 7/8"

the cars are raced on a 75' track

thank you so uch for taking your time to help me
(if u help me)

Also i will try to post some pictures of what the starting block i get looks like from CAD...

also am I able to upload CAD pictures to this forum?

We are not going to design it for you -- that's your assignment. What ways do you think you can optimize your car to be fast? What are the variables that affect how fast it can accelerate, and limit its top speed?

FAQ: Building the Fastest CO2 Car for School Project

What materials are needed to build a CO2 car for a school project?

The materials needed to build a CO2 car for a school project typically include a block of balsa wood, sandpaper, a coping saw, a drill, wheels, axles, and a CO2 cartridge.

What is the best design for a CO2 car to make it go faster?

The best design for a CO2 car to make it go faster is one that is streamlined and aerodynamic. This means having a sleek and narrow shape, with minimal drag and weight.

How do I attach the wheels and axles to my CO2 car?

To attach the wheels and axles to your CO2 car, you will need to drill holes in the bottom of the car body for the axles to go through. Then, insert the axles into the holes and secure them with glue or tape. Finally, attach the wheels to the ends of the axles.

What is the recommended weight for a CO2 car?

The recommended weight for a CO2 car is between 40-50 grams. This helps to ensure that the car has enough momentum to travel a long distance, but not too much weight that it slows down the car.

How can I make my CO2 car go faster?

To make your CO2 car go faster, you can try reducing the weight by sanding down any excess balsa wood. You can also increase the smoothness of the car's surface by using sandpaper and applying a coat of paint. Additionally, make sure the wheels and axles are properly aligned and lubricated for minimal friction.
