Question 6 5 pts How does the molecular structure of a wood

Question 6 (5 pts) How does the molecular structure of a wood cell affect the following properties of wood? a) Compressive strength parallel to the grain b) Shrinkage c) Tensile strength parallel to the grain.

Solution

Answer

Molecular structure of a wood is mainly responsible for its strength.

Generally wood is comprised of Grain layers

it affects the follwing properities

a) Compressive strength paralell to the grain

when compressive strength is applied paralell to grain it will fail easily and it has low strength in compression compared to tension and the material fails by buckling

b) Shrinkage

Molecular structure plays an important role in shrinkage by absorbing the liquids it leads to shrinkage very fast

it all depends upon molecular structure only.

c) Tensile strength paralell to grain

basically wood will resist more tension when we apply tension paralell to grain. Due to good bonding nature along the paralell grains it will offer more resistence to tension than compression.
