Fiberglass Insulation, R Value of 3.14. Pine board has an R Value of 1.74
Freshly treated Southern yellow pine treated with .60 CCA pcf will weigh 4.5-5 lbs per board foot.
The actual wood used could be almost anything, though pine is most common. Plywood is actually a type of manufactured wood with alternating layers glued together with their grain oriented perpendicular to increase the strength.
There are four main species of Southern Pine - shortleaf, longleaf, loblolly, and slash. Long Leaf Southern Pine is heavy, hard, strong and coarse grained. It is very durable when dry and well ventilated. It cannot be used in contact with the ground. It is used for heavy framing timbers and floors. Short Leaf Southern Pine can vary greatly in quality but is used as a substitute for long leaf pine.
No, pine is considered a soft wood. This is why many people cut down any that become taller than their homes.
Cedar the tensile strentgh of pine is less than cedar
parana pine wood is one of the most tensile materials on the planet
It is relatively strong. The measured ultimate tensile strength of stainless steel is 860 MPa. Tensile strength measures how much force is required to break it when stressed by being stretched or pulled. For relative comparisons the following ultimate tensile strengths are given: Stainless Steel ~ 860 Structural Steel ~ 400 Aluminum ~ 483 Silk ~ 1000 Pine wood ~ 40 Human bone ~ 130 Diamond ~ 2800 Concrete ~ 3 Hair ~ 380 Copper ~ 220 Titanium ~ 1040
The tensile strength of a material is the value at which the material fails when subjected to a tensile force. (Tensile means a force pulling the wood fibers lengthwise, as opposed to a compressive force.) There are a lot of different types and load cases for wood, so there is not one answer to this question. For example, wood used outside will fail at a lower load than wood inside. Wood is also anisotropic, i.e. it has different strength in different directions. Example values of tensile strength vary anywhere from 175 pounds per square inch for Utility Grade pine to 1400 psi for Dense Select Structural grade Douglas Fir. A good reference for material strength data for most species and grades of commerically available wood can be found in the American Institute of Timber Construction handbook.
About 20 pounds
Is dependent on span.
Harry Edwin Pine has written: 'State board questions and answers'
It would depend on the material the board is made from. 1 x 18 pine boards are used for wide shelves and can support a lot of weight, but will sag at lengths of 4 feet or more unless they are center braced.

What is the weight limit on a 2"x2" pine board before it breaks
No, pine is a soft wood. If you were to use any type of pine, it will make the board more susceptible to water damage and pressure cracks. ~ Cheers
Well you have not mentioned the thickness of the board so as a rough idea the weight of 10'x4 pine board with 12 mm thickness is appx. 60 kg. For complete answer you may ask experts at http://www.gharexpert.com Regsasrds
