The new bridge would help stop traffic delays and it would be easier to get to places without having to wait in traffic.]]> 2016-10-07 13:58:11 UTC https://padlet.com/1646943/6fvwgd4rr0u9/wish/129121946 1646943 https://padlet.com/1646943/6fvwgd4rr0u9/wish/129509141 IMAGINE
Me and my partner did some brainstorming, our first idea was to make sure we had an even support on both sides of the bridge. We wanted to make sure the bridge was stable on the top also. We knew we needed something that would hold the bridge up.
We decided to build a Truss Bridge because when we were doing research on different types of bridges we found out that the Truss Bridge had the most support and would be able to hold up very good.]]> 2016-10-10 13:38:45 UTC https://padlet.com/1646943/6fvwgd4rr0u9/wish/129509141 1646943 https://padlet.com/1646943/6fvwgd4rr0u9/wish/129512420 PLAN
Me and my partner faced a lot of problems along the way on building this bridge. One of our difficulties was trying to get the bridge to stay stable and make sure it would stay up straight. We also had trouble with the beam of the bridge. It wasn't strong enough to hold much. 
   The constraints of this assignment was that we could only use four sheets of paper, which is hard if you think about it. We could only use 2 feet of masking tape, which is a good amount. The big constraint was that we could not tape our bridge down on the testing platform.
  The criteria for this bridge was that it has to have a length of at least 12in, and a width of 3in, and it must support the weight of the pennies. The big criteria was that the bridge had to be built to where boats would be able to pass below the bridge.

We made circular supports like cylinders, they worked very well. The bridge stood up very good with the supports we had.
TEST RESULTS
Penny Stack-4
Penny Spread-7

The Penny Stack was the hardest because you had to make sure you had enough support and your bridge would hold a good amount of pennies. You would stack up 5 pennies at a time, in the middle of your bridge and when it would tilt, fall or touch the boats that would be you're number of pennies stacked. When we started stacking our pennies In the middle of the Truss Bridge, it started to tilt a little, like their was to much weight. 5 pennies was to much so we put 4 on their, an that's how many actually held up the bridge.

The Penny Spread was the easiest because the pennies would be spread out and it would put the same amount of weight on each side of the bridge. On our bridge, I thought it would hold up good, since we had a good support and the bridge was very steady.  When we were ready for the penny spread we took 5 to start off with, that did very good. Then we put 5 more on and it collapsed, so we took a few off and it turned out that 7 could only hold up the bridge.

I would build a different bridge to see the different kinds and ways you could make a better bridge. Trying other bridges could see which one would hold the most weight. I would add more supports because the more supports you have the more equal weight you have on the bridge.

Me and my partner collaborate very good, we gave each other our ideas and talked about different designs. If we both had a good idea we would find a way to put them together. Things we could better next time would be to have other ideas if our bridge didn't work out, because we had a little trouble in the beginning but we figured it out.]]> 2016-10-13 13:20:04 UTC https://padlet.com/1646943/6fvwgd4rr0u9/wish/130422732 1646943 https://padlet.com/1646943/6fvwgd4rr0u9/wish/130432916 Our Final Model]]> 2016-10-13 13:42:40 UTC https://padlet.com/1646943/6fvwgd4rr0u9/wish/130432916 1646943 https://padlet.com/1646943/6fvwgd4rr0u9/wish/130433086 Our Idea's]]> 2016-10-13 13:43:06 UTC https://padlet.com/1646943/6fvwgd4rr0u9/wish/130433086 1646943 https://padlet.com/1646943/6fvwgd4rr0u9/wish/130724592 2016-10-14 13:18:52 UTC https://padlet.com/1646943/6fvwgd4rr0u9/wish/130724592 1646943 https://padlet.com/1646943/6fvwgd4rr0u9/wish/130724889 2016-10-14 13:19:31 UTC https://padlet.com/1646943/6fvwgd4rr0u9/wish/130724889
