PROPERTIES OF WOOD 1 jimena05jgris https://padlet.com/jimena05jgris/2p3i4nunvckt/wish/215356022 Tensile strenght (resistance to streching) : it is good in the longitudinal direction (the direction of the grain) and poor tranverse direction.
Compressive strenght ( resistane to being crushed : it is the better in the tranverse direction than in the lungitudinalian direction.
Flexural strenght (resistance to bending : this is why it was used a lot in the past to make posts and beams...EX elm pinem ...
hardness: it depends of the type of wood,the structure and the cutting direction.Wood is not hard and this make it esier to work with.
thoughness: it is used in sports equipment like hockay sticks baseball bats...
thermal and electrical conductivity : it is very low.This is why wood is used to make handles and tools.
sound conductivity:used to make certain musical instruments.
colour:diferents woods have different colours: withe,yellow,dark yellow,brown,red,black,etc.
density:this is why it is used to builds ships.

COMBUSTION:advantage - must apply flame reterdant paint,disadvantage:wood burns easly.
MOIDTURE:advantage-the lower the humidity,the less decay and the wood will last loger,disadvantage:wood absorb moisture and this causes it to dilate.
ROTTING AND INSECT ATTACK:advantage-we can varnish the wood to stop this form happened,disadvantage-wood can also be attacked by insects,which lay eggs and then they lerve feed on it.]]> 2017-12-15 18:17:13 UTC https://padlet.com/jimena05jgris/2p3i4nunvckt/wish/216583924 WOOD PRODUCTS jimena05jgris https://padlet.com/jimena05jgris/2p3i4nunvckt/wish/216594241 MAN-MADE WOODS
