The first project, the rube goldberg
"Island Paradise"Here's a Video of it! |
The objective of our Rube was to lend a pencil to a friendBefore even deciding on our objective for our Rube Goldberg, Robert, Nick, Rachael and I had to do research on the whole subject of the Rube Goldberg. The definition of a Rube Goldberg is basically a set of complex and simple steps to achieve a simple task. Soon after learning about many important formulas like Force=Mass x Acceleration and simple machines like a lever, for example a see saw is a class one lever.

Breaking down each step of "island Paradise"
Step 2-The ball in the first step rolls into a small bucket and from the weight causes the other side of the string attached to a nail to rise and release a smaller ball.
The Mechanical Advantage is about 1 Simple Machine-Pulley Step 3-The nail is released and the marble rolls down the second inclined plane. The ball rolls down the inclined plane at 0.62m/s.

Reflection
After finishing the Rube Goldberg, there can be many different things I could say. I learned a few lessons, I got experience with building things that in real life and I also have even more ideas that I would have improved.
Throughout this project I had to work with three other people, Robert, Rachael and Nick. We at first had a slight difficult time working together, but we continued and did do well together. one thing I learned about myself was that I think I lead my group pretty well and listened to every ones ideas and compromise as much as possible. Some parts of the Rube Goldberg I would want to improve on would be some of the looks and the string on the pencil launcher. the looks were excellent to me in almost every place except for the weights and some extra pieces of wood in steps like 1-3. I thought the problem on the pencil launcher step, was that the strings would snap constantly when we didn't want them to and they were hard to set up. on the day of the class presentation, I decided to use two strings instead of one and they did not snap. I was glad, but I wish I could of done that for the presentation night. From this experience of building this Rube Goldberg with my group, I am very glad I di and would definitely do it again to make another design and learn from my mistakes. |
