=WOOD =

**Properties** Type: Spruce (softwood)
Strengths: Cheap, lightweight, moderately strong in compression and tension Weaknesses: Rots, swells and burns easily Bridges, houses, two- to three-story buildings, roller coasters Example: Son of Beast -- Cincinnati, Ohio You squeezed this block easily, but it took a lot of effort to make it break. Wood is cheap and pretty strong in compression. That's why people build houses out of wood! It wasn't easy to break this block of wood because wood is strong when you pull it in the direction of its fibers. It would have been three times easier for you to break this block if you'd stretched it from the top and bottom, across the direction of its fibers. = = ==
