Reverse Engineering
Reverse engineering is the reproduction of another manufacturer's product following detailed examination of its construction or composition. To explore this part of engineering we were split into groups of four. Within these groups we each chose our own item to break apart and explore. After learning about our own item we chose one of the four items to learn about in more detail. My group decided to learn more about a TI-30XIIS calculator. First we looked at the outside of the calculator and noted all physical features such as the plastic casing and the four screws holding the casing together. Next we looked at the inside of the calculator and tried to get what each part was and what function it had. As a group we then researched the function of every part and how they work together. After many days of research we were finally able to created a presentations and a report which we later presented to the class.
Below you can find our presentation and report.

Content:
Reverse Engineering: The reproduction of another manufacturer's product following detailed examination of its construction or composition.
Invention: The action of inventing something, typically a process or device.
Inovation: A new method, idea, product, etc.
Purpose: The reason for which something is done or created.
Hypothesis: A proposed explanation made on the basis of limited evidence as a starting point for further investigation.
Disassembly: To take something apart.
Functional analysis: Divides a system into smaller parts, called functional elements, which describe what the function of each part is.
Structural analysis: The determination of the effects of loads on physical structures and their components.
Interactions: A particular way in which each element affects affect one another.
Material properties: An intensive property of some material. For example stiffness, strength, and hardness.
Material analysis: A method of studying the nature of something or of determining its essential features and their relations.
Manufacturing analysis: Learning about the production of different objects.
Raw material: The basic material from which a product is made.
Forming methods: A particular manufacturing process which use suitable stresses which cause plastic deformation of the material to produce required shapes.
Joining methods: Joining materials to form a product.
Reflection:
Overall time management went best during this project. To stay on track we kept a detailed Gantt chart which clearly listed out all the deadlines we had for every component of our project. Thought this project we could have had better communication. We all completed our individual components of the project on time however we did not thoroughly discuss what we did. If we had talked more about what we were doing then we could have gotten each of our team members input and completed our tasks better. For example we all could have talked about the presentation and report which would have bettered both as some of us may have remembered an important aspect that others forgot.
Throughout this project I learned what a Gantt chart is. When I first heard that we were making a Gantt chart I did not know what it was however it ended up being a very useful tool throughout this project. For example we were able to double check when the presentation was due to make sure that we were able to complete it on time. I also learned that not everything can be found on the internet. For example my group was unable to figure out what exact kind of plastic was used for the outer shell of our calculator.
One thing that I could have worked on better and will continue to improve is playing a leader. We did not have a leader established in our group however I believe that a leader could have greatly improved our communication and helped us create a better presentation and report. I will also work on my individual time management skills. We got everything done on time however everything was done a little last minute.
