The goal of the Fire Away project was to build a trebuchet or catapult that launched a projectile as far as possible. It’s dimensions could not exceed 1 meter in any direction and the catapult had to stay on the ground. The device had to have a base that sits on the ground, two legs with an axle between them, and a firing arm with a load and effort end. Humans could set and release the catapult but not fire it themselves. The catapults will then be given to the Algebra 1 classes to use for graphing. Our trebuchet had the following dimensions:
With these measurements our catapult went an average of 20 meters. After conducting experiments on how to improve our catapults each group made modification based on the data. Our changes and reasons for modifications are as follows:
I am very pleased with how this project turned out. I belive that this project had the most succesful final results of any of the projects we have done so far. Our catapult launched the projectile one of the farthest distances. My team was amazing. We worked together nicley and had no fights or disagreements. I look forward to working with them again. I can safely say that we are all now friends. I enjoyed not having to do all the work, like I have had to do in previous projects. My teammates and I did and equal amount of work. It was wierd for me beacuse things were getting done with out me having to think about it. I enjoyed have collaberative and creative team. I feel fulied in the knowlage that we all did our best work. If I were to do this project over again, I would add in a bar in between the fork at the begining and take safey into mind. Me and one of my teammates eneded up getting hit in the hhear with the catpult arm. I will be sure to think of safey in the future. I can wait to start the next project: Creative Enginnering/solve a world problem. |
