‘Abstract’. What did you do and why was it important to you? What were your main findings from the project?
For my project, I wanted to design something that could attach to the human body to enhance it's lifting strength. I decided I wanted to do this when I thought about how extremely weak I am. Sometimes my family makes me move furniture or other heavy objects and I really don't like that. I'm really weak and lifting super heavy stuff is a real drag for me. I thought that maybe other people may have this problem too. Not everyone on this earth is a toned bodybuilder who can lift more than one of QA. Sometimes, lifting heavy things in a working environment can cause injuries or strain on a person. This inspired me to not only create something that was able to support a worker but to also give them extremely enhanced strength. To create this project, I needed to have a thorough understanding of how hydraulics worked. This is the method that I chose to give a person additional strength. Hydraulics work under pascals law which states that if a change in the pressure of a fluid occurs in one place, it is transmitted throughout the container. This can be applied to a hydraulic system. One side of the system which has a small area is pushed down. The other side will rise because the fluid cannot be compressed. However, this side has a larger area, and the force will be greater. This allows massive forces to be created from significantly smaller ones.
What were the main challenges for you doing this project? What were your strengths and what were your weaknesses?
This project had one main challenge for me. This was understanding how hydraulics worked and how they were applied in machines. As mentioned in a previous post, I wanted to model my design after a crane like this:
This is because both an arm and crane function to lift things. The hydraulics pistons allow it to expand and contract to move into position to lift an object. The main strength of my product is in the application of knowledge. I know how hydraulics work and was able to apply it to my own design. I was able to also apply previous units with my torque calculations which helped me determine how much the lift could hold. However, one weak point of my project is that it is not the most exciting. Media such as videos are particularly exciting because they can easily engage an audience with things like music or moving visuals. This is a bit harder to accomplish in a written piece. I tried to make my infographic look as nice as possible so that the audience wouldn't be bored out of their mind.
