Our first bridge was inspired off a truss bridge. We made our sides based off the strongest shape that is commonly used on bridges, and that is the triangle. We incorporated the shape throughout our bridge to help it withhold more weight.
We thought that the side of our bridge was the most important and strongest aspect of our bridge. We thought that this is our most important aspect because it was triple stacked and we thought it would help hold more weight.
Since our design is based off a truss bridge, the sticks will act in compression and tension as a unit. The force will interact with our bridge from the top, and it is trying to press down and bend inwards.
We changed the distribution of weight on our bridge by making it more connected to other sides of the bridge. We thought that it would make our bridge hold more.
We kept our side, the reason was because of the result from our first bridge, and that it stop the force coming from the top, and it helped balance out the weight and force which made the bridge from bending inward. The reason the bridge fell was because we didn't glue the sticks properly. Another thing that we kept was the top. It was the reason why our bridge was held together.
Our most important asapect and our strengths are our sides and our bottom, our sides are inspired by a truss bridge and it helps our bridge act in compression and tension together. Our bottom will help even out the weight throughout our whole bridge.
The weakness of our bridge we have a very weak top, it makes the connection to the bridge very weak, and we think that may be the downfall of our bridge. We think that with a lack of connection, all our bridge has to hold together is the bottom.
After our bridge broke, we realized that a good bridge needed a good bottom because in our second bridge, our bottom split right in the middle. We realized that a good side is needed because ours was able to help everything work in compression and tension as a unit, and this was able to help us hold more weight. A good top was needed too because it was the reason why our bridge was holding together, and it was the reason why our bridge was able to even hold the weight it did, which was 146 lbs. Good connection is also needed for a good bridge because in our first bridge, we failed to do that and that was why our bridge fell apart during the test.
