MTC Designing Lab

Intro
  This lab is to produce a fancy car that works with the engine(mouse trap) and some trashes that can be found in house. Ridiculously, our car must be in our own design and go farther than 5 m in order to get an A. Therefore, i had to pick an special design that no one uses it but i had to take a risk that it wouldn't go further

Hypothesis
   As the mouse trap on the top pulls the string, it rolls the wheel about 12 times; which the car should go a little bit more than 5m.

Working as a Group
  Since I wasn't live close to Christy, I had to call guardian to go all the way to her house. on Saturday and Monday, I went to her house and worked on the car together. Even though i had to do all dangerous jobs, such as making an holes on the can, or cutting the can, Christy helped me on making wheels and setting mousetrap.

Design
  Our design was the best of all class works since the monster can, duct tape, and the huge wheels made perfect harmony and no one's car looked like my car.

Relevance
  since ours in light and has huge head, air resistance was huge. Moreover, the cap was off when we did the trials so the air resistance would be worse.

Adaptation
  Well, I don't think i have used any physics in this lab. More likely my mouse trap car moved with the math: the length or the wheels' perimeter will be bigger than 5 meters. The only physics that I could use was the force of friction since I minimized the friction between the car and the ground by making the car light and the air friction by tilting it about 30 degrees.

Conclusion
This time, I focused too much on the design of the Car, so if i have another chance to make the MTC, I would simplify my design and make it to go way farther than my previous one.
