Abstract

Using just a single sheet of paper (8.5 x 11 inches) and up to five paper clips, can you build a bridge that will span 20 cm and support the weight of 100 pennies? The area beneath the span must be free (so that boats can pass beneath it). To test your bridge, place two books 20 cm apart, and set the bridge on the books, spanning the gap. Do not fasten the bridge to the book (nor to any other support). Does your bridge hold as much weight as you expected it would? If your bridge fails during testing, describe where and how it failed. As you're building or testing your bridge, you will probably get ideas for ways to improve your design. Try them out! When loading the bridge with pennies, does it matter if you spread them out evenly or put them all in the center? Why or why not? (WGBH Staff, 2000)

Career Profile
Have you ever visited family members for the holidays? You might have started your trip by taking the subway or a train to the airport. Then you jumped on a plane and flew to your destination. Finally, a family member picked you up in his or her car and drove you home. You traveled hundreds of miles in just one day. How did this happen? Who planned the subway route to the airport? Who decided the position of the airport runway? Who designed the highways and roadways? The answer to all of these… Read more

If you turned on a faucet, used a bathroom, or visited a public space (like a road, a building, or a bridge) today, then you've used or visited a project that civil engineers helped to design and build. Civil engineers work to improve travel and commerce, provide people with safe drinking water and sanitation, and protect communities from earthquakes and floods. This important and ancient work is combined with a desire to make structures that are as beautiful and environmentally sound, as they… Read more
Career Profile
The essayist and poet Ralph Waldo Emerson called Greek architecture the "flowering of geometry." Architects blend art and science, designing structures for people, such as houses, apartments, schools, stores, malls, offices, places of worship, museums, sports stadiums, music theaters, and convention centers. Their designs must take into account not only the structure's appearance, but its safety, function, environmental impact, and cost. Architects often participate in all phases of design,… Read more

Do you dream of building big? Civil engineering technicians help build some of the largest structures in the world—from buildings, bridges, and dams to highways, airfields, and wastewater treatment facilities. Many of these construction projects are "public works," meaning they strengthen and benefit a community, state, or the nation. Read more
