Bridge Engineering

 

One of our first stories we read in the year was the making of the Brooklyn Bridge in New York. We then formed up our own bridgebuilding companies and with a $1,000 in startup cash (Mr. D bucks) had to develop a bridge that could do two things: allow a matchbook car pulled by string to go up, across, and down the bridge that was covering a 1 foot river (the size of a floor tile) and two: hold up at least 200 pounds of weight! The winners got a free pass on an assignment in the future. Sticks were for sale from the popicle dealer (Mr. D) at one dollar a stick. They were free to make up any design that they think would work. Then Mr. D pulled mean tricks like pulling the car over the edge of the bridge if they didn't have guard rails and such. Finally the weight test. Usually we get a few that actually pass the test and we had one this year that passed the ultimate test! Mr. D was able to drive his truck OVER the bridge and it survived! That was one sturdy bridge!!
