What+we+have+Learned!

The first step in this whole process was to attempt to make our own cars. It was very difficult but we all managed to make one. We had to make many adjustments such as the chassis, gear ratio, wheels etc. At the end of making our cars they all went ten meters. Some went very slow and others went very fast. It all depended on the type of wheels you used or the gear ratio that you used. The most common gear ratio that we all used was small to big. The next thing we did was we started on making our car as a group based on the knowledge me gained while making our own cars. In the end we had a total of 7 models. On model one we used a gear ratio of 10 tooth to 50 tooth. Model two we used a gear ratio of 10 tooth to 60 tooth. Model three we used a gear ratio of 60 tooth to 10 tooth. On model four we used a gear ratio of 10 tooth to 20 tooth. On model five we used a gear ratio of 10 tooth to 50 tooth. On Model six we used a gear ratio of 10 tooth to 40 tooth. Finally on model seven we used a gear ratio of 10 tooth to 50 tooth again. We used a gear ratio of 10 tooth to 50 tooth as our final gear ratio because model one was the fastest model and its gear ratio was 10 tooth to 50 tooth. Some problems we came to while we were making our car were the gear on the motor was to big, so the gear would not move, the gears did not match up and the car was not going straight or fast. After we fixed those problems, our car looked ready to go. All we had to do was test it.
