Thoughness: This is the resistence of a materials to being broken when we strike it.
Deformability: This is the ability of a material to be deformed. The opposite of deformability is rigidity.
Ductility: This is the ability of amaterial to be stretched into wire.
Melleability: This is the ability of a material to be pressed  or rolled into a sheet.]]> 2018-11-21 10:00:33 UTC https://padlet.com/marcosfeijoog/1EMarcosFeijooSeverinoDonate/wish/306669839 5.Woods marcosfeijoog https://padlet.com/marcosfeijoog/1EMarcosFeijooSeverinoDonate/wish/307777654 2018-11-26 14:15:45 UTC https://padlet.com/marcosfeijoog/1EMarcosFeijooSeverinoDonate/wish/307777654 6.Metals marcosfeijoog https://padlet.com/marcosfeijoog/1EMarcosFeijooSeverinoDonate/wish/308392843 2018-11-27 17:05:38 UTC https://padlet.com/marcosfeijoog/1EMarcosFeijooSeverinoDonate/wish/308392843 7.Plastics marcosfeijoog https://padlet.com/marcosfeijoog/1EMarcosFeijooSeverinoDonate/wish/308394967 2018-11-27 17:08:43 UTC https://padlet.com/marcosfeijoog/1EMarcosFeijooSeverinoDonate/wish/308394967 8.Textiles marcosfeijoog https://padlet.com/marcosfeijoog/1EMarcosFeijooSeverinoDonate/wish/308396599 2018-11-27 17:11:07 UTC https://padlet.com/marcosfeijoog/1EMarcosFeijooSeverinoDonate/wish/308396599 9.Constructon materials marcosfeijoog https://padlet.com/marcosfeijoog/1EMarcosFeijooSeverinoDonate/wish/308397612 2018-11-27 17:12:38 UTC https://padlet.com/marcosfeijoog/1EMarcosFeijooSeverinoDonate/wish/308397612 10.Properties of wood marcosfeijoog https://padlet.com/marcosfeijoog/1EMarcosFeijooSeverinoDonate/wish/308400193 -Tensile strenght: It´s good in the longitudinal direction and poor in the transverse direcion
-Compressive strenght: It´s better in the transverse direction
-Flexural strenght: This was used a lot in the past to make pots and beams.
-Hardness: This can vary a lot. It depends on the type of wood, destructure and the cutting direction.
-Toughness: It is used in sports equipment.
-Thermal and electrical conductivity: Wood is a good insulator of heat and electricity.
-Sound conducivity: This is used to make certain musical instruments.
-Colours: Different woods have different colours.
-Density: Wood is a light material.]]> 2018-11-27 17:16:21 UTC https://padlet.com/marcosfeijoog/1EMarcosFeijooSeverinoDonate/wish/308400193 11.Wood products marcosfeijoog https://padlet.com/marcosfeijoog/1EMarcosFeijooSeverinoDonate/wish/308681727 Wood products include man-made wood and wood derivates.]]> 2018-11-28 09:46:28 UTC https://padlet.com/marcosfeijoog/1EMarcosFeijooSeverinoDonate/wish/308681727 12.Man-madewood marcosfeijoog https://padlet.com/marcosfeijoog/1EMarcosFeijooSeverinoDonate/wish/308685223 -Plywood: Is formed by veneers
