Rube Goldberg Machine – #3

 

During the designing process of our Rube Goldberg machine we had little difficulties. Our last step was the most geometric we transfered the force of three dominoes onto a small one domino. that domino hits a small plastic volleyball that rolls down a swirly ramp and going into a small knee-hockey goal. Overall, we had a very fascinating time together.

Reflecting on our team collaboration I personally think that we worked very well together as a group. Even though we occationally met we still got a lot done. We built a small sample on a poll table so it’s officially and apparently called “Pools closed.”

I think that we had a fantastic time together. When we finished our small sample we knew where we were headed and followed our goals our Rube Goldberg project is Great!

 

 

 

Rube Goldberg Machine – #2

Me, Graham and Drew had a very pleasant time together during this short period of time together. During our total 3 times of meeting together we got a lot done. We have our sketch down and a tiny experiment of our Rube Goldberg machine. Our procedure of making our experiment was easy. We started by pushing a small car down a steep swirly ramp that hit a car almost about to go on an escalator. Then the force of the car will transfer the force onto another car which proceeded on to the escalator. Then after it reached the summit of  the escalator the car falls on to a array of dominoes. The last domino has a string attached to it and that string is also attached to a huge popsicle stick.

Then, simultaneously the domino will drag down a row of popsicles causing a chain reaction. Then on the last popsicle stick we put one domino on it and right after the last popsicle stick is dragged down that domino goes along with it causing it to hit another row of dominoes. To access this short video please go to Graham’s blog post #1. Working on our sketch was easy because we had a lot of fresh ideas popping in our minds. In our sketch we included a short explanation of everything.

Our end goal is to make a small metal ball go down a maze which then it ends up in a small red box. (The toy is called Gravity Maze). I personally think that working in a group is better than working alone because you can have ideas here and there. Working alone sure you can be more efficient in time but your ideas may be boring. Thank you for reading my Post.

Rube Goldberg Machine – #1

We had our fist success on our machine on Monday afternoon. We were already frustrated by the fact that we’ve tried almost 15 times and recorded 2 fails in total but we eventually got 1 success. We had our sketch out but unfortunately we completely abandoned it and we wanted to test it from scratch. Our original idea was a total of 10 steps but as soon as we received the materials we knew we had a lack of them. During our fist day we completely fooled around and got nothing done. But fortunately we gathered all the materials we needed. Some difficult decisions we made were to find our 8 steps we had to create. Some more decisions we had to make was to where we were going to meet and schedule the time we meet.

I think the most important part of this project was the teamwork. It took a lot of innovation which is only helpful for the minds of future engineers.  This project helped all of us take our theoretical knowledge to the practical world. In multiple parts  Overall it was a great experience for our team for now.

Rocketry Reflection

This rocketry experience was delightful and entrancing, we obtained resourceful knowledge that would help us later on in our life. During the experience we worked cooperative mostly throughout the unit, but also had some tempestuous times during this experience.

Our first rocket was depressing, our rocket went the lowest out of all 5 rocket. We contemplated a long time to find what was wrong and it helped us along the way during the process planning of our second rocket. Despite that, we were still satisfied that our rocket launched off of the launcher. We used a ton of duck tape so that the rocket wouldn’t have any spaces that air could find it’s way out which we thought was the difficulty. The average height of our rocket was 71 feet and 21.5 meters high.

The second one accelerated way faster off of the launcher and we thought that made our rocket go to it’s summit. We had less arguments because it was our second rocket and had more information. We thought of another  the precipitate of our 1st rocket not going high: too much duck tape. We fixed all of our mistakes carefully. Our second rocket went 126 feet and 38.5 meters high. We placed 2nd out of all 5 rockets.

Thankfully we got a change to design a third rocket which practically resembles our rocket 2. That means it’s basically the same and there were near no changes. We kept nearly everything the same because we thought it consists a perfect amount of drag and thrust.

Overall this rocketry experience was pleasurable, exhilarating and absorbing. It has been a pleasure to work with my teammates throughout the unit.
