This is our bridge.

Summary

For this project, I'd say was quite difficult. Like I've said in the past, in this project, we are to create a bridge that can have a farmer, a fox, a chicken, and corn to cross over a 1 meter bridge safely. I'd say this project was difficult, because we had less building time, and the material to build the bridge was quite hard to build with. Before building, me and my group kinda brainstormed some different bridges types, and chose to do arch, with some combination of some parts of other bridges. Then, we decided to use penne pasta, because it has a harder and stronger than some other pasta. So we decided on a penne and spaghetti pasta, arch bridge. In this project, I have learned many things, like the 6 different bridge types, beam, suspension, arch, truss, cantilever, and a cable stayed bridge. Each bridge has 4 different types of stresses, compression, tension, torsion, and shear forces. Compression is the pushing of the bridge. Tension is the pulling force of a bridge. Torsion is the twisting force of the bridge. Shear force is when two structures was forced in opposite directions. Our bridge sadly, could not withstand the weight. The bridge collasped right away. But, my group and I learned not add so much weight, and we should different support systems. As you can see, even though the project was difficult, has less building time, bridge collapsing, we learned many things about bridges. 

Backward Looking

Did I have problems while working through this project? Yes. I had few problems while working through this project. For example, one problem was making the bridge. When creating the arch, it was unstable. I found a way to fix this, by add some supports under it. We needed a roadway, kinda last minute. Luckily, a group had extras, so they gave them to us. As you can see, I had a few projects, while working through the project. 

Inward Looking

After doing this project, I kinda felt proud and sad at the same time. For example, I felt sad, because some people in my group were stressed about this. So I decided to take it home. But after a few hours of work on this bridge, I thought it looked nice. Sadly, it did last very long. I also felt proud because not only did we get to build a bridge, I also learned many things about bridges and what we can do to make it better. And I like that we got to make a bridge. I didn't like that the main material of the bridge was pasta, which could break easily. As you can see, I felt sad and proud about this project.

Outward Looking

We had some similarities and differences with other groups with this project. For instance, some similarities are, we all used pasta. But, not all of us used the same type of pasta. Our group used penne pasta, lasagna, and spaghetti. Some groups sed lasagna too, but not all. There was one other group that use penne too. We also made an arch bridge, other made a truss bridge. Our process was quite similar, because we all had to do our research, then we all brainstormed ideas, then create our bridges. As you can see, we had some similarities and differences with other groups with this project.

Forward Looking

If we had a chance to do this project, we would. For instance, instead of doing an arch bridge, we might make a truss bridge or a shorter bridge, so that the bridge would be more stable and sturdier. Even though, we were given a 1 lb. box of spaghetti, we might not use it, because spaghetti breaks too easily. We might not use penne pasta, either. Even though penne is stronger, it's too strong. You can glue it together, but it will break again. So as you can see, if we had a chance to redo this project, we would do it and change some parts.

Project Blog : Victor Nguyen 7A Image Summary For this hat project, I have learned many things. For instance, I have learned the main thing about electromechanical engineer. That main thing, is that they design and build electronic circuits, for video games, amusement parks, airplane circuits, etc. To become that engineer, you can study at mainly any university, but you need at least a Bachelor's degree, with 4 years or more in college. Electromechanical engineers have to work up to 40 hours a week and they get paid up to $120,000. Some companies have electromechanical engineers, like Texas Instruments, Intel, etc. Backward - looking Before I got assigned this subject, I didn't know much about this topic. I probably knew what an engineer is, but not an electromechanical engineer. For example, I knew engineers design and build different things. In the name, 'Electromechanical Engineer' is electro, so I thought this engineer design and build things that have to

Sound Amplification Project Blog : Victor Nguyen 7A Image/Links: Our finished device Link to Manual:  https://docs.google.com/a/oakgrovesd.net/document/d/1ExTEDaXqIdBsOPZ7hHIS_zR0nLNrBYs_zjVFvatH8qc/edit?usp=sharing Summary At the beginning of the project, we assigned/chose our groups, which is me, Pierson, Abram, and Ben. Our task was to create a device that was portable and could amplify sound, in a room or party. In order to create a prototype, you need to have multiple ideas, just in case. We learned having many ideas was a good thing, because sometime you could be wrong and have more to come. Everything in the middle was the same, because we had to build a prototype. But after we tested, we learned that holes needed to covered up to prevent any loose sound from coming out.  Near the end, we had to make an ignite presentation. We learned that we had to do a maximum of 15 slides and have it advance every 15 seconds, which will be under 2 minutes. Instead, we made

Eco-House W4 - 2/3/17

Weekly Blog : Victor Nguyen 7A Design Process This week, with my group, I am on Communicate Final Design. I, with my group are finishing, and wrapping up our project. Summary This week, I would say we have done many things. This whole week, we continued to finish of model of the eco house, and started on finishing the project. For example, on Monday, we were not at school, no work was done. On Tuesday, we had Ben and Jewel finish the house. So they did. Me and Minh Anh worked on our individual real estate flyers. On Wednesday, since now that our whole team is here, we had more help. We didn't have much time, since it is Wednesday. We each did our own part, either on the flyers, starting on our video, or finishing the house. On Thursday, we were in Ms. McMillan's room, for 3 periods to learn about video editing from CreaTV. On Friday, we writing our blog. If we have enough time, we are continuing to work on our project. As you can see, we have done many things this wee
