Base of our bridge
The base of our bridge is very strong. It is built of a dsign we put a lot of thought into. The bottom will have units of 5 popsical sticks then connected by one horizontal stick. This way we can make 6 of those and connect them cogether with stocks sticking out to add on our sides.
Sides of our bridge
The sides of our bridge is made up of the trusses, and the beams. The beams basically connect the top of the bridge to the actully bridge base. The sticks that stick out through the base, the sides can stick through the sides providing the sides to stay up and hold all the tension.
Our second bridge we used a triangle system to make our beidge strong. A triangle made out of popsical sticks sideways is very weak were as a vertical triangles are very hard to break. We used five triangles on both sides connected by sideways sticks to keep the bridge up and strong.
The base of our second bridge, was made up of popsical sticks, where five go next to each other then are connected by a sideways stick. Five more sticks are put on top of the layered base as well. These sideways sticks are used as the platforms for the sides to connect to where the the base has to break before the sides.
The main part of our design was under part with sideways interlocked popsical sticks. These are very strong and hard to break. By having this underneath our bridge, it will keep the bridge strong and sturdy. With this beam under the bridge. The top of our bridge will be compressed together and the beam will limit this. The day before testing this part was named illegal and we were unable to use the strongest part of our bridge.
The bottom of our bridge will take lots of tension and expand, this would have been handled better if our support beam would have helped it stay up
