Rubber Band Powered Car

[sciencerox]

I need some help with my construction of a rubberband powered car.

 

Plan

 

-I decided to use plastic to construct the frame.

-I would be using 5 pieces of plastic to construct the frame, like a 3-D rectangle withought the bottom part.

-I would be attaching a little pin to the front axle and a eye hook to the back axle.

-The pin and the eye hook is used to have the rubberband attached.

-The wheels would be turned and then the rubber would be wound up and the car would move.

 

 

Help needed

 

-I need to know what materials to use for my wheels and axles.

-Whether my plan above would work.

-More suggestions would be greatly appreciated.

Hello sciencerox,

 

This has been covered a few times already. Don't forget to try the search feature within Hypography. :lol:

What are your goals? Navigation requires destination. Nature keeps score.

The teacher wants us to make the car on the spot in a period of 10 minutes. And the distance between the starting line and finishing line is 4 metres. The closer you are to the 4 metres mark, the higher the grade.

Please avoid opening new threads when you can post new, but parellel questions in those already existing. Thanks.

Oh,ok. Sorry for starting a new thread about this. I thought that we could post threads about the same topic again. So sorry. I won't do that again.

[InfiniteNow]

No worries. Technically, you can open a new thread. However, it'd better if you keep same questions in same thread, and start new threads when the question is on a different topic. :)

If you have time to add complexity, you could add some light wire and a brake so that vehicle would stop right at the line.

 

 

Light thread that would wind up on one of the axels and pull the brake. easy to calibrate, if you have enough power in your bands.
