Help! Problem with my SOLAR CAR?
Question:
Our car is pretty fast when compared to those made by other groups, but the main problem is that it keeps tilting and turning all the time so it runs out of the track almost every time. The track we're supposed to run on is 1 foot wide and about 20 feet long.
Our car originally had only 3 wheels for higher speed, 2 at the back and 1 in the front. Then we found out that it's very unstable, sometimes running towards the right and sometimes left, running out of the track all the time. So we gave it 4 wheels instead, but now its speed has significantly reduced, and it's still very unstable. Now we don't know whether giving it 4 wheels instead of 3 is a right choice or not.
Help! What should we do!? Now we have 2 goals:
1) Make it run in a straight line, at least it wouldn't run out of the track again.
2) Make it even faster.
First thing is you are going to want to check to see if the weight is distributed properly and if the car itself is straight.
