Need help with impossible Bridge Project! Desperate.
Posted 25 September 2006 - 11:53 PM
<b>1.)</b> Bridge must be of one single unit construction.
<b>2.)</b> A one-inch cube must be able to pass under the bridge through the longest part parallel to one side of the bridge with one book on the bridge (each book weighs around 2 pounds). You may only use a ruler to push the cube under the bridge. When loaded with weight, the bridge must not touch any part of the floor.
<b>3.)</b> The brdige must be constructed of only ONE sheet of paper
<b>4.)</b> The bridge must have a mass NOT to exceed 10 grams. 50 points deducted from grade for ever gram above 10 grams.
<b>5.)</b> Only glue will be allowed to hold the bridge together (any kind)
<b>6.)</b> Bridge supports must only be made of glue and the paper. Glue sticks in their solid form are not allowed.
<b>7.)</b> Grade is based on the number of text books (7 1/2" x 91/2") supported by bridge freestanding for ten seconds.
<b>8.)</b> 3 points awarded for every textbook supported.

I had an assignment in high school where we had to use nothing but a manila folder to hold a large amount of weight. The only adhesive was glue.
My idea was a simple cone (weight distributed downward and evenly across the entire structure). Keep in mind that the best and strongest structures are made of triangles, cones (or tapered cylinders), and arches. With that knowledge alone, you should be able to come up with something that will withstand at least a few textbooks if you're even half decent as a structural engineering student.

problem solved. A++ in my book.
Please, take the time and do some research and find out how much it would have cost you to get your help from a decent paid-for source. A "roll-of-the-dice" freelancer will charge you $5-$15/hr. A decent entry level freelancer will charge you around $15-30/hr. A professional will charge you anywhere from $50-$100/hr. An agency will charge anywhere from $100-$250/hr. Think about all this when soliciting for help here. Think about how much money you are making from the work you are asking for help on. No, we do not expect you to pay for the help given here, but donating a few bucks is a fraction of the cost of what you would have paid, shows your appreciation, helps motivate people to keep offering help without the pricetag, and helps make this a higher quality free-help community
