PAPER BRIDGE COMPETITION
(GROUP PROJECT)

OBJECTIVES:
To construct a free span paper bridge that is capable of supporting a number of weights. The best score is achieved by total weight supported.

SPESIFICATIONS:
The bridge must be constructed from only paper and tape. Standard 4 pieces A4 paper size up to 80 GSM only can be used. The bridge span must be the A4 paper width.

Glue can be used to join the members; for example, along the seam of a tubular member or at a point where two or more members come together.

The sheet of paper may be cut into pieces and re-assembled as desired. Parts may be rolled, folded, or slit.

The total weight of the bridge must not exceed the weight of 4 pieces A4 80 GSM paper.

When in use, the bridge ends must be laid freely on the support. 20mm at both ends must be free from any features; this is for the bridge support. A square platform size 40mmx40mm must be provided for weight loads.

Competition:

Each bridge will be inspected for materials used in the construction and for the use of glue. It will be weighted as well.

Once the bridge is qualified, the length of the bridge will be measured. Fail to follow the rules will lead to the disqualification, and the group will score 0 for competition mark.

After the length measurement is taken, the students will begin to stack the load (range of 0.1N, 0.5N, 1.0N, 5.0N weighted) on its load point. A student must add a load platform size 40mm x 40mm minimum that will be placed horizontally on the top of the bridge in order to support the load. It can be made of paper board or similar material.

The loads are to be added one at a time, each can going on top of the previous load, until the bridge is crushed, or no longer capable of supporting the load. The total weight is considered up to the previous load added before collapsed.

Scoring of the competition:

The length will be

    Cooper’s stress calculations were made for the smaller length of the bridge. Cooper then recalculated the stress and discovered that there would be 7% more stress on the bridge. However, the Phoenix Company design staff and Cooper, recalculated the stress as team and discovered that there was 10% more stress. There were many financial problems with both the Phoenix Bridge Company and the Quebec Bridge Company, once they finally figured out the need to revise the assumed weights that were overlooked. The issue with the loads were discovered a year later, when a large portion of the bridge had already been built. Therefore, Cooper made the executive decision to accept the heavier loads and stresses to be within the acceptable limits. Cooper’s only alternative would have been to scratch the entire project and start over, and he did not want to stain his…

    Each type of design is although, unique in its own way, fulfills the desired goal that the Truss Brides are made for. The purpose of this experiment is to research various bridges and build a similar one that gave the students the highest inspiration. For one case in particular, the bridge design was in-spired by the Pratt Bridge and almost every height, width, and length met the requirements ex-cept for the length on the bottom part of the bridge, it exceeded the maximum height that was asked. Moreover the bridge held a total of 20 pounds before one of the top sticks snapped. Alt-hough it performed a decent job, the bridge could have held more weight if there were more di-agonals to provide more support so the bridge wouldn't break. Furthermore, this bridge fulfilled its goal and held a large amount of weight for such a small bridge. These bridges are also very significant for this planet because it is very resourceful and effective, as well as…

    Because we started this project a little too late, we did not bring any bridges to the actual contest, but we still followed most of the guidelines that they came up with. The goal was to make a bridge that could hold the most weight but also it needed to be light.The bridge had to span over 48 inches. My partners were Kat and Ema. At first, we started to think of designs to make a bridge. Our first design, after calculating how much wood it was going to take, came out to be a very large amount of wood that we could not use. Even though we trashed the idea, we kept the base idea that we had because it was pretty efficient. After around two more designs, we came up with a bridge that would not take that much wood and we believed that it would hold a good amount of weight. The first thing we did was cut out all of our pieces that we needed to create the bridge, this took a long time to calculate and to cut the right size pieces. At the same time of us finishing cutting all our of pieces, a new rule came into play that we could create smaller bridges to span over 12 inches. We cut every piece we had into ¼ of the size. We began creating our design but due to the glue not being very good and a lack of time, we did not finish. We still tested our design and it ended up being one of the best bridges that was made in our class. We decided that if we would have tried this again, we would use our time more wisely. I liked how we were able to make our own design, and how we could use a good amount of wood to create it. I also liked that we were not rushed to do this project. One thing that I would change is that we need to focus on one project at a time. This would allow us to make better designs. I would also change the type of glue that we used because it did not hold very well. The last thing that I would change is that I would like to pick my partners in the…

    Brief Summary: A four-lane bridge in Washington has collapsed, dumping an unknown number of cars and people into the icy river below. The bridge is located approximately 130km from Vancouver and it is a main route for Canadian’s to cross over to the USA. It was not known what caused the collapse of the bridge, but State Patrol detectives and the patrol's commercial vehicle enforcement bureau troopers were talking late Thursday night to a commercial truck driver whose rig was believed to have struck the structure."It appears the commercial vehicle made contact with the bridge," Washington State Trooper Mark Francis said. "Whether it was the cause of the collapse or made contact as the bridge was falling, it appears it hit the bridge." The bridge was not classified as structurally deficient, but a Federal Highway Administration database listed it as being "functionally obsolete" -- a category meaning that the design is outdated, such as having narrow shoulders and low clearance underneath. The bridge was built in 1955 and has a sufficiency rating of 57.4 out of 100, according to federal records. That is well below the statewide average rating of 80, according to an Associated Press analysis of federal data, but 759 bridges in the state have a lower sufficiency score. The NTSB is now investigating.…

Well, I certainly have and I know that I don’t want for a bridge to fall down whenever I am driving or walking across one. It was 6:05 pm, the rush hour in Minneapolis, Minnesota and the unimaginable at the I-35W bridge occurred. On August 1, 2007 the 1,907 foot long bridge collapsed leaving dozens of cars and trucks trapped and in the Mississippi River. The accident left 13 people dead and caused for 145 to be injured.

    After a bridge is put into use, gradual deterioration is inevitable because of loading, temperature changes or other environmental factors. In order to guarantee the safety and durability of those bridges which are expensive and closely related with people’s livelihood, long-term and continuous structural health monitoring is an essential part of the maintenance management. Among the various structural performance evaluations, vertical deflection is an important parameter that can directly and effectively indicate a bridge’s…

    Abstract- The development of De-Sauty’s bridge for capacitance measurement has been followed by various modifications and improvements in the original circuit. Lately Schering bridge and transformer ratio arm bridge have been used for measurement of capacitance in a circuit. Today there is instrumentation available that makes use of these bridges in real life such as that can measure the quality of electrical insulation at power frequency as well as in touch-sensitive sensors. This paper presents an understanding of bridges to measure capacitance, their real life implementation , various errors in measurement and the required cautions to avoid errors.…
