I am building a bridge for my class and need some help in the design of the bridge. Here is a list of the items I get:
1.) 100 toothpicks
2.) 200 feet of string
3.) 25 feet of aluminum foil
4.) 10 paper clips
5.) 10 rubber bands
6.) 1 Roll of Scotch Tape
7.) Pair of scissors
8.) 12" ruler
9.) hole punch
10.) 10 pieces of construction paper
11.) 10 note cards

The bridge has to span 5 feet and hold approximately 100 pounds on top of the bridge. I only get 30 minutes to build this bridge in class also. I will have 7 people helping me.

Also, what is the best design in case the weight is hanging from the bottom instead?

Please help.

Now you have learnt how to use computer control desing a small model that you could make that could be controlled using the computer. Explain what your design is and how it would work. This should be completed on a separate sheet. < what do you think this means or what shall i do?

I had heard that air travels faster over the top so that a void isn't created, as the air that travels underneath has shorter to travel, but I don't buy that. There's nothing that forces two air molecules at the front of the wing to join each other at the back of the wing.
