Today i started the first design the group design looks like this:


The Fantastic Four Design Idea

 This is what the string looks when the string is attached:

I first got my groups and they are danelle, mollie, avni,zena. i got our assesment and then i tested the speghetti and then i did the sketch on the piece of paper my design has a picture of the speghetti bridge and the design: this is my design idea: Glue four 5-cm long pieces together to make a square. Make another square, now with a 7-cm long piece connecting opposite corners. Test both constructions by squeezing them in the direction of the arrows. You see that the square built of two triangles is much stronger. It doesn't even make much difference whether you press in the direction of the red or the green arrows. Now for the real thing. If you connect a number of triangles you can make a beam that is strong and light at the same time. Like this: Let's try out different constructions. There are different ways to make a bridge from a series of connected triangles. Here you see several examples, which we called, M-, W-, V- and inverted-V-constructions:
