-Toughness: this is the resistence of materilas to be broken when we strike it.
-Deformability: this is the ability of a material to be deformed.
-Ductility: this is the ability of a material to be stretched into a wire.
-Malleability: this is the ability of materials to be preesed or rolled into a sheet]]> 2018-12-02 13:54:43 UTC https://padlet.com/asd222/1A_ESO_DANI_ARAUZ/wish/310159971 4.TECHNICAL MATERIAL asd222 https://padlet.com/asd222/1A_ESO_DANI_ARAUZ/wish/310161878 Any material used to construct an object.

Depend on the type (hard-soft).The climate and humidity where the tree came from...
-Tensile strength: good in longitudinal direction.
-Compresive strenght: good in transverso direction.
-Flexural strengh: It's good, but better in transverse direction.
Use to in construtition and structures.
Trees - ash, fir, elm and pine.
-Hardness: vary. It depends on the types of wood, the structure and the cutting directión
-Toughness: It´s tough. It's used for sports equipment.
-Thermal and electrical conductivity: It is very low. Wood is a good insulator of heat and electricity.
-Sound conductivity: Good, it's used for musical instrument.
-Colour: Different woods have different colours. It's used to make furniture.
-Density: Is a light material. Floats. It's used to build ships.]]> 2018-12-02 14:22:41 UTC https://padlet.com/asd222/1A_ESO_DANI_ARAUZ/wish/310163297 5.PROPERTIES OF MATERIALS asd222 https://padlet.com/asd222/1A_ESO_DANI_ARAUZ/wish/310163685 -Sensory properties.

  • Plywood
  • Chipboard
-Wood derivatives are usually obtained from leftover wood(chips, sawdust, etc).
  • Paper
  • Cardboard
  • Cork

Depending on the percentage of carbon are
  • Iron (carbon-less 0.1%)
  • Steel (carbon-0.1% to 2%)
  • Cast iron (carbon-2 % to 6.67%)
-Non Ferrous materials 
  • Copper (good conductor, highly resistant, ductile and malleable).
  • Tin (ductile malleable easy to work and to melt)
  • Aluminium (very light, resistan, good conductor, non toxic, ductile, malleable and easy to shape)
  • Zinc (malleable, ductile, good conductor, very resistant)
