Bridge Testing

Today for inquiry we were testing our speghetti bridges and my group started off first. We put the bridge on a stable platform and had eight bricks to weigh down the bridge to make it snap, the aim of this activity was to see how many brick's it would take to hold and the type of bridge, for example there was a beam bridge, truss bridge, or some other bridges. Our speghetti bridge held three bricks and broke on the fourth one and the span of the bridge was 26cm, the next group had a span of 28cm and held only one brick, the next group had a span of 26.5cm and set a new record with five bricks. The next group held one brick and the span of their bridge was 42cm, the next group had the biggest bridge because their spam was 50cm and held two bricks. The group after that one had a small bridge with 16cm of spam and held three bricks so that was pretty cool to watch, there were heaps of of other groups that did testing on their bridges but the bridge that was most successful was Lyric, Tiava, Mataio, and Julians bridge because their one held all eight bricks and didn't move once, there structure was really good and really strong because they built a Truss bridge, and a Truss bridge has triangles for in its design. Triangles are the strongest shape and that is why their bridge could hold all eight bricks.
