Over millennia, human-built structures have become bigger, more complex and quicker to build. A key to this has been understanding how forces behave. This clip looks at two types of opposing forces -- tension and compression -- defining them and presenting a range of real-world examples and how those forces impact on structural design. It is an ideal resource for secondary and vocational students of design and technology.
