Stable Structures

The C.N. Tower is 1815 feet tall. It is one of the tallest buildings in the world. It has a glass floor in the tower. It was made in 1976 to be used as a T.V. and communication tower. It took 1,537 workers who worked five days a week, 24 hours a day to build the CN Tower. It took more than three years to build and it cost 63 million.

A frame makes the shape of a structure. A post and beam with a triangle is the strongest shape.The basement is called the foundation.

Every structure needs to be stable. It needs to withstand the force of gravity. There are 3 different design techniques. They are the triangle, arch and post and beam.

We made a bridgewith posts at the bottom. We also used posts and beams to support the structure. Every structure needs to withstand the force of gravity. We shook the desk with the brige on it to make shure it would not brak or fall apart.

    Alright, almost there. You need to check spelling carefully and punctuation. All sentences need to start with a capital. Add a few more facts to your famous structure. You are also missing a summary of your build. Love the background, you should label your diagrams too!
