Cardboard Chairs Description
The aim of this mini-project was to make a chair that could support 150 pounds entirely of cardboard and nothing else, meaning no glue, tape, etc. This seemed really tough yet once designed it was a piece of cake. We designed a full size chair that we specifically created to make it strong, look nice,and comfortable. For example are chair back-rest was angled at 110 degrees, a good sitting position. To provide good support we focused as much as we could on the seat, where the pressure/compression would matter the most. From there we brought all the pieces together at the headrest of the chair to also bring more stability, but to the back of the chair instead.
Mini-Concepts
Tensile Strength - The resistance of a material to breaking under tension
Compressive Strength - The resistance of a material to breaking under compression
Center of Gravity - A point from which the weight of a body or system may be considered to act. In uniform gravity it is the same as the center of mass
Structures - The strengths of the support systems

Reflection
Post project, I think this would've been a great success if we took the time to research all and the best way to make a cardboard chair. Even though our chair was perfectly fine, we could've made a much better one. I also think that the type of chair each group made reflected the resources they brought or were given. Without the three base pieces we got, we would not have been able to make what we had planned. During this project I learned that triangles are reasonably stronger than rectangles in terms of structure. Another thing I learned was that while making your chair even the slightest mistakes can make a big difference, such as too big of a cut or too small. One thing I could've done better was researching more before throwing things together and seeing if it works. Also, I should've used a single piece for the seat instead of two in the picture above. One piece would provide more strength than two thin pieces, but due to the limited sizes in cardboard we couldn't find one that would satisfy this entire seat. In all I think that our group made a great chair with what we had.
