How Do Structures of Rigid Eggshells Affect Their Strengths and How Can This Be Used in Designing Temporary Shelters?

Overview

Objectives/Goals The purpose of my project is not only to test the strength of different rigid eggshells, but also to try to create an affordable, easy to construct, and overall better temporary home. Methods/Materials Three different types of eggs, emu, chicken, and quail, were tested to determine their strength against impacts of varying mass and height. Through equalizing equations and ratios the eggshell shown to be the most resilient was used as the bases for my shelter. Results After equalizing my data I found that the emu egg was the strongest of the three eggs. However, I chose to use the quail egg in designing my structure because it possessed more favorable attributes and was the most resilient. The quail egg when hit with a weight it couldn't withstand caved in, but was still serviceable unlike the emu egg which shattered at failure. Conclusions/Discussion I concluded that strength isn't the only indicator of something's durability, it is one of many. I decided to go with the quail egg because it was not only strong, but also flexible and light weight.
