2013 Spaghetti Bridge Test

Pinwheels, pigs-in-a-blanket, miniature cheeseburgers and crab-stuffed mushrooms are all examples of finger food entrees you might consider. Compression pushes the bridge inward, preventing it from being pulled apart. To create complex bridges that hold a lot of weight, such as arch bridges or truss bridges, you're going to need an adhesive to hold the spaghetti together. Cover the paper with a clear plastic film, such as plastic wrap, and use it as a template. We can then test them by applying weights to see when they break.

Fifth grade Lesson Spaghetti Bridge Challenge

The goal here is to see if you can build a stronger bridge capable of holding more weight. Keep your compression members short and stocky if possible. Trusses are triangle-shaped support beams that attach point-side down to the roadbed of the bridge on either side. Miniature fancy cakes traditionally called petits fours, cupcakes or danishes are all finger food desserts that would be appropriate and that your guests will enjoy. You can explore my reasoning on this throughout this website. A traditional snack found at bridge parties is made from a combination of a well-known breakfast cereal and nuts. For example: a beam bridge can take great weight over a short distance, truss bridges take advantage of the strength of the shape of a triangle, while suspension bridges can handle torque and tension across a long distance.

Then they test their bridges to see how much weight they can carry before breaking. The heavier your bridge is, the more likely it is that it will collapse when extra weight is applied. Since I am a civil engineer, I guess they thought I have a lot of experience with bridges not! Who makes sure they are safe for us to use? Which material and shape will work the best? Grade Level: 4th - 6th; Type: Physics, Engineering Objective: This project explores the basic physics of bridges. This bridge used hollow tubes constructed of spaghetti for the compression members. Grades 6 - 8 Do you agree with this alignment? Take care to protect the surface under the bridge in case of collapse.

How to Build a Spaghetti Bridge

Tension and compression forces in a truss bridge After learning about bridge types, students should have some idea of which type of bridge best balances the weight. But there are many forces beyond these types of motion. Then, based on your previous testing, determine what kind of spaghetti element you need to put there in order to adequately resist that load. If the bearing point is not flat, the bridge may twist and break. How would you use them? For a college level project, I would expect to see your load testing results for individual spaghetti members i. Yes No Thanks for your feedback! There are cited in this article, which can be found at the bottom of the page. These tools can be used to clip the spaghetti strands together, allowing them to dry - hands free! 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.

Days 2-3 or 4: Students should construct their bridge Final day: Test the bridges Tips for implementing lesson: Designate an area for students to dry their bridges. Have students record how much weight their bridges withstood before they failed. This area should be flat and smooth. The Johns Hopkins University Press, Baltimore. Some flexibility in the pasta helps to redistribute weight across your bridge. Spaghetti is not very strong in bending! Have a garbage can ready to place the broken bridges in Have rubrics ready to go Do not allow students to trade or borrow glue; these are the constraints on the challenge.

Spaghetti Bridges (for Informal Learning)

When in a contest, typically the bridge is tested for strength halfway across with a dowel across the travel surface. He's frequently at odds with his group mates about their effort and the precision of their work. Cucumber sandwiches and ham spread sandwiches are two very simple recipes to prepare and make that your guests will enjoy. How can you test these forces? Hands-on engineering projects: the design, construction, and testing of spaghetti or aluminum bridges or domes. Yes No Thanks for your feedback! Let's start with the supplies.
