【Blog#2】tall structures

Yesterday I built up a tall structure with Jess and Linda. First we thought that to make a stable structure, the base should be a close-to-triangle structure. So we rolled the newspaper and fold it to make a triangle structure as the base. Then we tightly rolled the rest of the newspaper (so the roll would be longer and taller) as the body of the tower. at first the structure cannot balance itself, but we don't want to kill the height of it, after our little discussion, we found out that the tower cannot stand because the top part was so heavy, so we decided to flip it over, we flipped the top of the newspaper to the bottom and taped it on the base so it stayed stable.




Now the question asks for the physics of tall structures, according to my experience, I'll say that the physics I tested out from the challenge is the mass of weight. As I said before, if the top part is heavier than the bottom part, the structure wouldn't be balanced. The less weight at the top, the more balance the structure will be. Another words, the base is important, the top is also important. We all know that the base should be heavier and bigger, such as the structure of a tumbler. But we often ignored the top part which is also an important part of the entire structure. as a result, the mass of weight is one of the physics of tall structures. For the second question: what makes a tall structure. I think this question is a bit similar as the first one. As I mentioned before, the more weight at the bottom, the more balance the structure will be. So for the purpose of making a balance tall structure, the first thing we'll need is a heavy and big base. And again, the body part should be light to make the whole structure stable. To sum up, the heavy base and the light body make a tall structure.



The centre of gravity is a geometric property of any object. In other words, the center of gravity is the average location of the weight of an object. For different shapes of objects, the centre of gravity is also different.
