Mini Trebuchet Project
For this project my group chose to base our trebuchet on ancient Egypt around the year 43 B.C.E. How we represented this on our trebuchet is by drawing hieroglyphs on the sides on it, even though non of that would have been historically accurate. The greatest soft skill that I had during this project was creativity because I came up with the idea to base our trebuchet off of ancient Egypt. The area that I could have improved on would be critical thinking because I didn't really think throughout this project I left it mostly to my group especially when we were in the middle of the project I noticed that I didn't help my group when they came to a problem finding the counter weight.

Rube Project Reflection
During this project, we constructed a rube Goldberg by using three different simple machines methods. For example, some of the machines we used along with many different examples are pulleys, levers, wedges, wheels, axles, also inclined planes and screws. An example of how my group used some of these simple machines is where a car would roll down an inclined plane and land in a bucket which made the bucket drop activating another simple machine which was a wheel and axle known as a car. Our rube also demonstrated some physics principles including potential energy, kinetic energy, inertia, momentum, and speed. Some examples of these are when we had our car that we used was moved down a hill witch created kinetic energy when the car was reaching the next stage it hit at the bucket that had potential energy. Afterwards, this energy then turned into kinetic energy.
Starting a rube by dropping a small steel ball 0.5m, you have to know how much energy it would have. If the ball weighed 0.007kg, the ball would have Potential Energy of 0.034335 joules. You get this by multiplying the weight by height by gravity. When the ball is about to hit the ground, you can calculate its Kinetic Energy. You would get this by finding the joules. Say the velocity is 45cm/s. You would convert this into meters, giving you .45m/s. Then you stick this in the equation 1/2mv^2. This will result in 0.00070875 joules of kinetic energy.
The design process started with a drawing of what we wanted our part of the rube, Goldberg, to look like and from there we figured out what parts fit together the best so we should have a working rube. After we figured out how we were going to build the rube we had to work out the materials and everything we needed to build. But before we started building our final rube we built a threepart rube to help us understand the concept of how to build a rube and how the point of a rube is based around some form of a joke.
