| What is a I-beam? | An I-beam’s shape gives it strength. I-beams have less weight than solid beams of the same length. Because they have less of their own weight to support, I-beams can support larger loads |
| What is a column? | A column is a solid structure that can stand by itself. Columns can be used to support beams and I-beams. |
| What is a truss? | A truss is a rigid framework of beams joined together. Trusses are usually in the form of interlocking triangles. |
