Newspaper Structures

Our group's structure. (:

Each group was given 5 sheets of newspaper and some masking tape to build the tallest structure possible. Ours came in second.

Physics of Tall Structures: By making the lower part of the building heavier, it is able to support the weight of the higher, lighter levels. Also skyscrapers are supported by an underground substructure. Then, the weight is supported by vertical steel columns. Finally, horizontal steel girders support the weight of each floor.

Our structure didn't spread out the weight very well, but it still was able to stay standing.

What makes a tall structure stable? Spreading the weight out, steel supports, making the base larger than the top, etc..

Our structure wasn't completely stable, but it didn't fall down unless it was blown on.

What is the centre of gravity? It is a point on an object where the weight is equally balanced in all directions.
