Wood
Plank
A plank is a piece of timber, flat,
elongated and rectangular, with parallel faces,
higher or longer than wide, used in the construction
of ships, houses, bridges, etc...
Usually from sawn timber, more than 38 mm thick,
and generally wider than 63 mm. If the width
is less than 63 mm and the thickness less than
38 mm is called board.
Since ancient times planks sawn from logs were used
to build bridges, walkways, ships or houses, including
flooring, coverings and furniture . They also served
as a support to form a shelf or table (for storing
food, objects, etc...). It originates in the habitat
of the Neolithic house, the shepherd used them to
cure the cheese (let them dry on long planks).
The plank has been in the past, the basis of maritime
transport. The planks of wood float on the water,
and they are easy to be machined, so, during many
centuries, they were used as the "primary material"
in ship building, until they have been replaced
by other materials (steel, aluminium, fiberglass,
etc..) in modern times.
