Plywood is a composite material manufactured from thin layers, or "plies", of wood veneer that have been stacked and glued together. It is an engineered wood from the family of manufactured boards, which include plywood, medium-density fibreboard (MDF), oriented strand board (OSB), and particle board (or chipboard).
The density is typically between 500 and 1,000 kg/m 3 (31 and 62 lb/cu ft). [5] The range of density and classification as light-, standard-, or high-density board is a misnomer and confusing. The density of the board, when evaluated in relation to the density of the fibre that goes into making the panel, is important.
Plywood and OSB typically have a density of 560–640 kg/m 3 (35–40 lb/cu ft). For example, 9.5 mm (3 ⁄ 8 in) plywood sheathing or OSB sheathing typically has a surface density of 4.9–5.9 kg/m 2 (1–1.2 lb/sq ft). [48] Many other engineered woods have densities much higher than OSB.
A 2011 discovery in the Canadian province of New Brunswick yielded the earliest known plants to have grown wood, approximately 395 to 400 million years ago. [5] [6]Wood can be dated by carbon dating and in some species by dendrochronology to determine when a wooden object was created.
The density of hardboard is higher than 500 kg/m 3 (31 lb/cu ft), [4] usually about 800–1,040 kg/m 3 (50–65 lb/cu ft). [5] It differs from particle board and medium-density fiberboard in that the bonding of the wood fibers requires no additional adhesive, the original lignin in the wood fibers sufficing to bond the hardboard together, [ 6 ...
The short ton (abbreviation tn[ 1 ]) is a measurement unit equal to 2,000 pounds (907.18 kg). It is commonly used in the United States, where it is known simply as a ton;[ 1 ] however, the term is ambiguous, the single word " ton " being variously used for short, long, and metric tons. The various tons are defined as units of mass. [ 2 ]
The mass of an object is a measure of the object’s inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s 2.
1.12 short tons (exactly) The long ton, [ 1 ] also known as the imperial ton or displacement ton, [ 1 ][ 2 ] is a measurement unit equal to 2,240 pounds (1,016.0 kg). It is the name for the unit called the " ton " in the avoirdupois system of weights or Imperial system of measurements. It was standardised in the 13th century.
