This is a picture of my friend Samer, standing on two cartons of eggs. Most people think of eggs as being very fragile, but this is not the case. Just like in bridges and building, eggs utilize the strongest shape there is: the arch. Eggs have shapes that are unique and similar to a 3 dimensional arch. An egg?s strength lies at the top and bottom. When a force is applied to these locations, the pressure is distributed all around the egg. Alternatively, when a force is applied to the side of the egg, for instance, cracking an egg on the side of a bowl, the pressure is concentrated at that point. All of the eggs are pointing up in the carton which is why Samer is able to stand on them without them breaking. Samer?s weight (the force) is distributed evenly over the ?arch? of each egg. If the eggs were not all placed in the same facing directions, the yoke would have been on us.
