Rube Goldberg Machine Our rube Goldberg machine was made by John Kosta, Vivian Leida, Luis Jasper, and I. The theme of our project was music. The objective of our machine was to ring a bell at the end. Many elements where music related. Our machine was about 1.25 maters tall by 0.75 meters wide. It included 3 inclined planes, 1 screw, 1 wheel and axel, 1 pulley, and 1 lever for a total of 7 simple machines. These machines were symbolized by a guitar, thin pieces of wood, pvc pipe (flute/recorder), small pieces of wood (wood blocks), a funnel (trumpet bell), a bike chain, small pulley, and another small piece of wood. It had 10 steps in total for the project. It consisted of mostly wood, and it took about fourteen hours from start to finish. The art included a guitar, a flute, the bell of a trumpet, and wood blocks. The flute is a pvc pipe, the bell of trumpet a plastic funnel, and wood blocks to simply resemble wood blocks. The main Physics concepts we used for our Rube Goldberg Machine were mechanical advantage, force (Newton's), and speed/velocity (Meters per seconds squared). We calculated the mechanical advantage of the pulleys by seeing how many times the string wraps around the wheel. We found the mechanical advantage of the levers by using output force divided by input force and output distance divided by input distance. We had to find the force of many elements such as the marbles, and the wooden blocks. Also, we had to calculate how much force many elements would take to perform their needed tasks. We calculated every force by multiplying mass times acceleration. Another very important piece was to find the speed and velocity of the balls. In order to find this, we had to find the speed and velocity of the balls by measuring the distance the ball traveled and the time it traveled for. Them we used the speed and velocity to find forces. The physics of this project are very related to math. Every step we did and every calculation involved math. The final project was also related to English because of the power point and posters. Along the way there were ups and downs to this project. Things that went well were the ramps, the funnel, and lever. The reason they went so well was because they were the simplest. All the ball had to do on the ramp was roll and down it and same with the funnel and lever. The more complicated parts of the project were the pulley and wheel and axel. The pulley was hard because it kept facing the wrong way and not going all the way down. The wheel and axel was tough because the we had to get it to move a small amount and knock a ball down a ramp. It was hard to get it to move without the wheel coming off the track. There was also ups and down with our group mates during the project. We were really good at working together and collaborating with each other. the only small hiccup we had with collaboration sometimes was agreeing on certain ideas and time management. For the most part collaboration was never a problem because of how cooperative my group mates were. This was our very first of many projects in the STEM program. I learned a lot about physics, engineering, designing, construction, and teamwork throughout this project. I really enjoyed creating our Rube Goldberg project and look forward to many more projects in the future.
