The Squeeze Is On

Through hands-on group projects, students learn about the force of compression and how it acts on structural components. Using everyday materials, such as paper, toothpicks and tape, they construct structures designed to (hopefully) support the weight of a cinder block for 30 seconds.
When civil engineers are asked to design a building, one thing they must calculate is the total compressive load that will be at work in the structure. To do this, they take into account the anticipated loads resulting from how people will use the building and the weight of the structure itself. Based on these calculations, materials with appropriate properties for carrying the weight are chosen, and structural components (such as columns and beams) are designed to provide adequate support and weight distribution.
- Students gain insight into structural supports designed to withstand compression.
- Students develop construction skills.
- Students learn about the fundamental loads.
