Egg shock: Why does horizontal traps protect the egg!
Egg shock: Why does horizontal traps protect the egg!
Cambridge, USA - researchers at the Massachusetts Institute of Technology (with) in Cambridge have a widespread assumption of the fragility of eggs over the pile: the way an egg falls influences whether it breaks or not. As part of the so -called "Egg Drop Challenge", a popular experiment in schools, it was examined whether a raw egg breaks on the side when falling on the side. The results of this study, published in the journal "Communications Physics", show that eggs are less fragile when they fall horizontally.
For their investigations, the research team dropped a total of 180 eggs from different heights. It turned out that over 50% of the upright eggs broke out of only 8 millimeters in a case, while less than 10% of the horizontal eggs were affected. These results remained the same at larger heights: the probability of a break is significantly lower in the horizontal case.
physical explanations and misunderstandings
To explain these phenomena, the researchers used a special device to measure the pressure that the eggs were exposed. It turned out that eggs in the middle are more flexible, which means that they can absorb more energy before breaking. Due to the horizontal case, you can intercept about 30% more energy than in an upright case. The researchers pointed out that there is often toughness and stiffness between the physical properties. While eggs are stiffer when compression vertical, they are not tougher and therefore less fragile.
The results of this study not only provide information about the fragility of eggs, but also illuminate the basic concept of mechanics. This aspect is part of the content of the "Experimental Physics I" course, which is offered at RWTH Aachen. This course conveys the basics of classical physics and includes topics such as measurements, point mechanics and elasticity.
practical relevance in training
As part of the "Experimental Physics I" course, which is offered in the winter semester and is accessible to students in the first semester without special prerequisites, experimental demonstrations are in the foreground. This practical learning promotes the understanding of physical phenomena, which is particularly important for students of material sciences.
In summary, it can be said that the results of co-research not only encourage an academic discussion about the fragility of eggs, but also find practical applications in the physical training of students. The findings could potentially also be relevant for the design and safety of products that aim to flexibility and energy absorption.More details about research can be found in the article by Kölner Stadt-Anzeiger href = "https://www.spiegel.de/wissenschaft/wo-bricht-das-ei-wenn-es-faellt-a3986-bf1d-4a0e-8f30-22369BB73CC7"> SPIEGEL offers additional information.
