Wood



Wood is an organic material, Strong in tension and compression.

Uses: Wood has many uses, some of them are:
 * As fuel
 * In construction
 * Furniture and utensils
 * In the arts( musical instruments)
 * toys

Basic notions of wood structures  The principal solid system, called log construction, is employed when only primitive cutting tools are available  The skeletal system requires precise cutting and shaping of lumber.  The half-timbered structures are made up of wooden elements interwined.  The furniture joints generally are solved joining wood to wood, using glues to attach them together

Physical Properties of wood  Anisotropy  Moisture  Electrical properties

Mechanical properties of wood  Elastic properties  Strength properties

Conclusion:  Huge enviromental benefits, because its biodegradable.  Versatile.  Can resist tension and compression.  Excellent qualities and properties.  Enviromentally responsible.
