"Building Towers" Shape and Structure PPT Courseware 4

The Eiffel Tower is an open structure iron tower built in 1889 and located on the Champ de Mars in Paris, France. It is 320 meters high. The Eiffel Tower is named after its designer, bridge engineer Gustave Eiffel. The tower has a bizarre and unique design and is a technical masterpiece in the history of world architecture. It has therefore become an important attraction and prominent symbol in France and Paris.

Now let's look at these towers. What do they have in common in shape and structure?

What forces does such a tall tower have to withstand?

guess

The bigger the bottom, the harder it is to fall

The heavier the bottom, the harder it is to fall

Frame structure has stronger wind resistance

The more the foundation sinks into the ground, the less likely it is to collapse.

How to put plastic bottles in the easiest way to pour them?

Why are plastic bottles so hard to pour?

How to do it, plastic bottles are the least likely to be poured?

What methods can we use to make objects less likely to fall?

Build a "tower" that won't fall down easily:

1. Discuss methods of designing and building tall towers.

2. Group discussion:

①Which materials to choose? Consider the characteristics of the material.

②What method is used to make the tower difficult to fall?

③Our tower design drawing.

3. Tower building requirements: Make our tower tall and stable.

4. Time limit is fifteen minutes.

Bearing force:

1. Its own weight and other pressures;

2. Withstand the force of wind coming from the side.

Features of frame structure tower:

1. The top is small and the bottom is big, the top is light and the bottom is heavy;

2. A large number of triangular frame structures are used;

3. The open frame structure has strong wind resistance and low air resistance, making it difficult to fall down.

Through the experiment, do your results match your conjecture?
