What Is the Best Design for a Pasta Bridge?

spaghetti bridge design ideas

By giving students specific roles, it's clear what each student should be doing and when. He's frequently at odds with his group mates about their effort and the precision of their work. For a stronger bridge, try making your sides triangular and using a few layers of pasta for the base of your bridge. Use a string or bent paperclip to attach the container to the center of the bridge. It all depends on what kind of bridge you are building.

Think about having a class discussion before the project starts. Find one in your area and sign up. During the bridge project she wants to sit and watch her group work. This article was co-authored by. Now that the support structure is in place, you need to measure the distance between the two sides of the support structure to determine the length that your bridge will need to span. Again, the size and density of the weighted objects will depend on the size of the bridge you built. Each of these designs, along with the host of variations, was developed for a specific reason or to make better use of existing or new materials or construction methods.

Spaghetti Bridge Competition Hints

There is a relationship between the weight and strength of your bridge. In that case, you would want to make a lot of triangle or crossing shapes, like a parker bridge or a double intersecting warren bridge. These engineers must consider many variables when creating plans, such as the distance to be spanned, where the bridge is being built, the expected type of traffic it will have to withstand, materials available, budget and what the bridge will look like. The hint here is to make the compression members as short as practical, by adding internal web members. The bridge connections should be strong but flexible due to spaghetti's brittleness. Allow students to initially design their bridge on paper, and make a hypothesis about why they think this structure will support the most weight.

Draw your bridge design full-size e. As stated above, epoxy is the strongest bonding agent you can use. The purpose of building a spaghetti bridge is to apply the theoretical principles of engineering to a real-life construction project. Tony, on the other hand, seems to want to take charge. Ask students what they should hear and what they should see if groups are working well together. Then, as a class, create a histogram showing how much weight each bridge held.

To expand their knowledge of forces, consider teaching students the forces that hold a bridge up - compression and tension. Yes No Thanks for your feedback! However, this will increase the chances of you accidentally collapsing the bridge when placing weights on it, so be very careful. Also, leave the middle layer of pasta in the base unglued, so that it can shift weight across the bridge and hold more weight. It depends on how much time they have to build their bridge and how complex you want the bridges to be. Place a bridge so it spans across the gap between two tables. See more ideas about Spaghetti bridge, Bridges and Bridge design. Like any good science experiment, a little trial and error will be necessary.

For smaller bridges, coins will work as weighted objects. So, good luck my Quora friend and may your best bridge win. Then, use epoxy to glue the pieces of pasta together, since it's strong and dries quickly. You can learn more about each of these by clicking the link above. The following tables show the current records for each division: Division Record Load Ratio up to and including grade 10 26. Grades 6 - 8 Do you agree with this alignment?. Grades 6 - 8 Do you agree with this alignment? Establishing group norms will help the project run smoothly.

Grades 6 - 8 Do you agree with this alignment? Grades 6 - 8 Do you agree with this alignment? A span is the length of the bridge from end to end. Compression strength is usually governed by buckling, which depends on the slenderness ratio. But there are many forces beyond these types of motion. This article was co-authored by. Currently you have JavaScript disabled. The type of glue you use will make or break your bridge. For spaghetti bridge-building contests, the weight of the bridge itself matters, and the winner is the bridge with the highest strength to weight ratio.

If the bearing point is not flat, the bridge may twist and break. Although no charge or fee is required for using TeachEngineering curricular materials in your classroom, the lessons and activities often require material supplies. Tension opposes compression, pulling the bridge apart and preventing it from caving in. This obviously makes for a less sturdy bridge, but the same general principles of engineering can be gleaned from the exercise. While some bridge competitions require that you build your bridge on-site, others may require you to bring an already built bridge to the competition. Each spaghetti bridge building competition is different and, as such, will employ a different system of applying weight to the bridge to make it collapse. Try to predetermine the approximate load your bridge will carry.

Who will be doing what? Then, slowly increase the length of your bridges as you learn how to build them successfully. Epoxy dries up firmly and will provide the best support for your bridge joints. Analysis After the student bridges are built, it's time to test them. Note: The card roadway and model car need not be included in the final test weighing. Model airplane glue and hot glue from a glue gun are easy to apply, but are slightly more flexible when they dry. Of course, you can some what virtually design your bridge and test the load bearing with 3D software such as Solidworks, Rhino 3D, Autodesk, however those feasibility simulation are useless without accurate test date, as they say: Rubbish in, Rubbish out. Many brands of epoxy dry in five minutes or less.
