There are more than half a million bridges in the United States, and you rely on them every day to cross obstacles like streams, valleys, and railroad tracks. But do you know how they work? Or why some bridges are curved while others are straight? Engineers must consider many things -- like the distance to be spanned and the types of materials available -- before determining the size, shape, and overall look of a bridge. Learn more about bridges and bridge design with the activity that follows. Research bridges so you can learn which bridge type will hold the most weight!

You will not find all of the answers on any one page.  In addition to the websites given, you may find information on additional pages.  All answers should be in complete sentences, and in a separate Google Document. The file name should be: (class period).(your last name).bridge if I were doing this assignment my file name would be: 0a.bowen.bridge..

1.    List and describe each major type of bridge.

2.    What are the strengths and weaknesses of each type of bridge?

4.    What is a span?

5.    What is compression?

6.    What is tension?

7.    What are 3 other forces that act upon bridges? Give technical name (in parenthesis) and explain each.

8.    Why do engineers need to consider these forces when they are designing bridges?

9.    Name and describe three types of loads that must be considered in bridge construction?

10. Compare and contrast a beam bridge and an arch bridge.  List at least three ways they are similar and three ways they are different.
