The best way to design your bridge is to first look at the different types of bridges built by engineers today. Bridge engineers try to solve exactly the same problem that you are with your project: Design an attractive structure which optimizes weight and cost. I suggest that you browse around the web and look at the different types of truss bridges that have been built around the world. After you have found some bridges you like, then you can pattern your model after them.

Good glue is a necessity for strong spaghetti structures. I suggest a fast-drying epoxy type glue for maximum strength and workability. Wood glues are also good, but take a long time to set. If you decide to use epoxy, be very careful with it. You don't want to glue yourself or your dog to the furniture.

Another hint is to cook the spaghetti and the let it dry. It gets much stronger. You can also form interesting shapes (like cables) when it is wet. Your teacher may not allow you to do this though.

You might also try downloading the "West Point Bridge Designer" program at http://www.dean.usma.edu/cme/civilsoft.htm This is a great program for learning about truss bridges and will no doubt impress your teacher.

Good Luck! Richard Pickings, P.E.

I'm another Physics student, and I really enjoy the class, but my teacher is particularly tough. I had him for integrated Chemistry, and Chemistry1 and now Physics too. I've always maintained an A in his class, so it's really important that I do good on this project.

We have to build a bridge out of spaghetti noodles, and glue, that's it, the bridge that holds the most weight,best design, and lowest gross weight get a prize. I need some useful tips to help with my bridge.

Thanks!!!

DO NOT USE WOOD GLUE its water based
