What is Available material? - ANSWERS-An available material is simply the
convenience and ease of acquiring.
What is the Wood section of the tree? - ANSWERS-The wood section of the tree is
composed of sapwood and heartwood. The heartwood is made up of dead cells that
provide structural strength for the tree. Note: The sapwood is the outer region of the
trunk and contains new, living cells and acts as a storage of water and nutrients for
roots.
What is the Pith? - ANSWERS-The pith is the central core of the tree
, What is Anisotropic Nature of Wood? - ANSWERS-Wood is anisotropic material. This
means that it mechanical and physical properties like strength, stiffness, and shrinkage
in wood are different in different grain directions.
What are the Moisture Contents of Wood? - ANSWERS-The three moisture conditions
of wood are green, kiln dry and oven dry. Wood that has just been cut is known as
green wood. Kiln dry and oven dry both involve the use of heat treatment to reduce the
moisture content of wood. Kiln dry is typically 12% MC and and oven drying eliminates
almost all the water and is very brittle.
What is Dimension Lumber? - ANSWERS-Dimensional lumber include 2x4, 2x6, 4x4,
4x6
What is Economics in material? - ANSWERS-Factors that should be considered in the
economics include: Availability and cost of raw materials, manufacturing costs,
transportation, placing, and maintenance.
What is a Sustainable material? - ANSWERS-Sustainable design is the philosophy of
designing physical objects, the built environment to comply with the principles of
economic, social, and ecological sustainability.
What is strength? - ANSWERS-Strength of a material is its ability to withstand an
applied load without failure or plastic deformation. It considers the relationship between
the external loads applied and the resulting deformation.
What is Deformation? - ANSWERS-Deformation refers to changes of the shape or size
of an object due to applied forces or change in temperature.
What is an Elastic Behavior? - ANSWERS-An elastic material is one that deforms
immediately upon loading, maintains constant deformation if load is held constant, and
return immediately to its original undeformed shape when load is removed.
What is Stress? - ANSWERS-Stress is a measure of the internal resistance in a
material to an externally applied load (F/A).
What is Strain? - ANSWERS-Strain is a measure of the deformation produced by the
influence of stress (Deformation/Original Length).
What is Poisson's Ratio? - ANSWERS-Posson's Ratio is a measure of the amount by
which a solid "spreads out sideways" under the action of a load from above (Lateral
Strain/Strain in Direction of Load)
What is Linear Elasticity? - ANSWERS-Linear elasticity where the relationship between
stress and strain is proportional, or linear.
