| 説明 | In honor of National Engineers Week 2013 U.S. Army Corps of Engineers Europe District employees present structural engineering, alternative energy and fire protection topics to Wiesbaden Middle School students Feb. 19-21 in Wiesbaden, Germany. Lawrence Carabajal, a district structural engineer, presented bridge building concepts to eighth-grade science and math students. Carabajal used a hands-on approach, constructing a Leonardo bridge for students to test and recreate. Students were eager to assist in testing the capacity of the bridge by adding textbooks to determine the applied load the structure could withstand without failing or breaking. Later, the students were asked how to strengthen the bridge. The answer, provided by one engaged student, was reinforcement. Using their feet, students created an embankment to support the bridge allowing for a much greater applied load (more textbooks) than the previous bridge could hold. The demonstration provided a key lesson in tension versus compression, a concept critical to bridge design and construction. It was also an opportunity for USACE to come into the school and expose the students to real-world applications of what they learn in the classroom as it relates to science, technology, engineering and math or STEM.
