A platform that can be raised
We are going to make a bridge with a platform that can be raised. The structure will be made with triangles of paper only
![Page 3: Eng Puetne De Tubos](https://reader036.vdocuments.us/reader036/viewer/2022062523/548ed24db47959486e8b4818/html5/thumbnails/3.jpg)
Before we start with the bridge we are going to do a resistance test on the traingulated structures
Triangles resistance test

In order to do this project we need these materials:
• Paper• Thermofuse glue• Cord
• Plywood
Triangle resistance test
![Page 5: Eng Puetne De Tubos](https://reader036.vdocuments.us/reader036/viewer/2022062523/548ed24db47959486e8b4818/html5/thumbnails/5.jpg)
First of all we will make the paper tubes. You roll the paper around a wood bar.

Then glue the edge with a little glue. Take care because if you use too much, it will get stuck to the

Since our tower is 30cm high we have to make:4 tubes 30cm long16 tubes 10 cm long16 tubes de 13 cm long
4x 30cm
16x13cm16x10cm

With the tubes you will form two sides of the tower
Make two of these

In order to connect the bars properly try to make a gap at the end of the shortest bars

Once you have two sides you can start joining them together like in the picture

Remember that the more triangles the stronger the structures will be

Triangles resistance test
Finally we will put all the towers together to make them more resistant.
The board has to be 30x40cm in order to cover 6 towers
![Page 13: Eng Puetne De Tubos](https://reader036.vdocuments.us/reader036/viewer/2022062523/548ed24db47959486e8b4818/html5/thumbnails/13.jpg)
Triangles resistance test
We will check the resistance of our triangles¡¡

Triangles resistance test
You have only six days to finish it, so
Let’s work
![Page 15: Eng Puetne De Tubos](https://reader036.vdocuments.us/reader036/viewer/2022062523/548ed24db47959486e8b4818/html5/thumbnails/15.jpg)
A platform that can be raised
Now that we know how to make triangulated structures we are able to build a platform that can be raised
![Page 16: Eng Puetne De Tubos](https://reader036.vdocuments.us/reader036/viewer/2022062523/548ed24db47959486e8b4818/html5/thumbnails/16.jpg)
As you did before, once you have two sides you can start joining them together like in the picture

Triangles resistance test

A platform that can be raised
Attention¡¡¡¡¡This time we have to leave a
gap where the platform will be placed
![Page 18: Eng Puetne De Tubos](https://reader036.vdocuments.us/reader036/viewer/2022062523/548ed24db47959486e8b4818/html5/thumbnails/18.jpg)
A platform that can be raised
This is the handle that will move our platform
20cm
3cm
8cm
5cm
![Page 19: Eng Puetne De Tubos](https://reader036.vdocuments.us/reader036/viewer/2022062523/548ed24db47959486e8b4818/html5/thumbnails/19.jpg)
A platform that can be raised
The platform has to be 20x10cm and you have to make it as you did before
10cm
13cm
20cm
Cover it with a piece of paper
![Page 20: Eng Puetne De Tubos](https://reader036.vdocuments.us/reader036/viewer/2022062523/548ed24db47959486e8b4818/html5/thumbnails/20.jpg)
A platform that can be raisedThe platform form will be made with
tubes and has to be movable, so make sure that one tube can be placed inside the other
5cm
![Page 21: Eng Puetne De Tubos](https://reader036.vdocuments.us/reader036/viewer/2022062523/548ed24db47959486e8b4818/html5/thumbnails/21.jpg)
A platform that can be raised
Then you need to insert the crank inside the tower, using two tubes of 3cm diameter
Cranck

A platform that can be raised
Finally you only need to connect the platform to the tower with a cord, making a knot at both ends
