Join us on March 13 for the fifth of 10 online, interactive events, presented by MOREnet, MODOT and RoundTrips.
Date: March 13, 2009
Times: 9-9:50 a.m. and 10-10:50 a.m.
Grade Levels: 7-12
On Nov. 7, 1940, in what may be the most dramatic footage of a bridge failure ever caught on film, the Tacoma Narrows Bridge in Washington collapsed while being pounded by wind. Luckily no one was injured. On April 5, 1987, after days of record rainfall and floods, the Schoharie Creek Bridge in New York collapsed killing ten people. On Aug. 1, 2007, during the height of rush hour traffic, the I-35W Bridge collapsed in Minneapolis, plunging dozens of cars and their occupants into the Mississippi River.
Why do seemingly well-designed bridges suddenly collapse? How do forces, both natural and man-made create stress and cause bridge failure? What’s the science involved in these events?
In this program, your students will interact with engineers and investigate these and other real-life bridge failures. Learn about stress points, important elements in design and maintenance and how natural forces like wind, rain and river flow affect the life of a bridge. Find out what engineers do to counteract those forces and create the best bridge design possible. Join us for our fifth program in our continuing series produced with the Missouri Department of Transportation as they build a new bridge over the Missouri River at Glasgow, Mo.
