Compression: The act of pushing something into a smaller space
Tension: The act of stretching or straining an object; applying force
Equilibrium: A state of rest or balance due to the equal action of opposing forces
Rigidity: If a triangles three sides are fixed, then the triangle must never change shape
History: The Great Pyramids of Giza is still standing because of the architectural design called the angle of repose, which is made of granular material and is the steepest angle of the the descent relative to the horizontal plane of which material can be piled without collapsing. The stone were perfect right angles that will not tilt. That is why the pyramid does not lean to one side.
The Eiffel Tower is still standing because of the different layers of bars that create structurally safe triangular formations. It is slim at the top and gets wide and wider towards the bottom, which distributes the weight across the entire spire.
The Space Needle is still standing because of a simple concept called the center of gravity. The space needle's center of gravity is practically on the ground. The lower center of gravity, the more stable an object is. Knowing this the builders were able to make a very tall, very stable building.
Materials: Elmer's glue, Popsickle sticks, Tape, and Manila folders
Materiales- Pegamento, Palos de Paleta, Cinta, carpetas
Step 1) Arrange popsicle sticks into triangles and glue together.
Paso 1) Ponemos juntos las palos de paleta a las escuadra, pegamos con pegamento este juntos.
Step 2) Stack these triangles atop each other until structure is 12 inches tall. Paso 2) monton el triangulo encima cada otros hasta estructura es 12 pulgada alto
Step 3) Tightly roll a folder into a tube form, tape it together then place in structure. Paso 3) bien rollo a carpeta en a tubo forma cinta juntos entonces lugar en estructura
Step 4) Lay 10 sticks side by side atop the structure. Paso 4) poner 10 trozo de madera lada al lado de lada encima el estructura
Step 5) Separately make a two by two square of popsicle sticks stack till 4 inches
Paso 5) Por separado para hacemos una plaza de pasos de polo hasta 4 in. alto
Step 6) Cut 1 inch pieces of popsicle sticks and shove between the already stacked sticks.
Paso 6) Para contamos 1 in. piezas de pasos de polo y maleta entre los parte superior pasos de polo.
Step 7) Repeat step five on a small ledge Paso 7) repete paso 5 en a pequeno alfeziar
Step 8) Repeat step 6
Paso 8) repeate paso 6
Research: There are a multitude of factors that make buildings strong...
The shapes used: The most stable shape is the triangle, due to its three points of failure. All other shapes have more than three weak spots. the smaller the angle, the more tension it can withstand. a triangle can have three 60 degree angles, making the strongest points stronger than any other shapes.
The center of gravity: The center of gravity is a very important part of a structure's survivability. The lower the center of gravity, the harder it is to destroy. If your center of gravity is in the middle or at the top, it will eventually topple over.
The materials: Some of the strongest materials in the world are stone, brick, iron, steel, granite, and especially marble. Marble, stone, and granite are the strongest because metals can bend under extreme heat, whereas rocks cannot.
Explanation: Our supportive section of the structure is made of popsicle sticks glued together into triangles. The most durable shape is a triangle, with only three points of failure it is the harder to destroy. We alternated the direction the triangles pointed throughout the tower because it creates resistance from every angle. The paper and tape exterior will assure weather resistance and prevent breakage. For stability we have the pyramid base, we used this shape because the structures that we researched have proven to be extremely durable. Our stacking method made achieving the height easy.
