MEL is lumber where a parameter like density is evaluated nondestructively by mechanical grading equipment to predict certain mechanical properties. A MEL machine evaluates each piece and sorts each piece into various strength classification grade categories.
Deflection and stress, moment of inertia, section modulus and technical information of beams and columns.
Weights of green, kiln dried and pressure treated lumber boards.
Commercial softwood lumber dimension chart - nominal and actual sizes.
Properties of structural lumber.
Combustion of wood and firewood heat values for species like Pine, Elm, Hickory and more.
Red Spruce, Longleaf Pine and Douglas Fir - moisture content and their compressive strength.
The density of wood versus moisture content.
Bending and compression strength of wood species used in beams.
Safe loads for wood columns.
Soft and hardwood - the Janka Hardness scale.
Weight supported by a double or triple wood headers.
Allowable withdrawal load force.
Densities of various wood species - apple, ash, cedar, elm and more.
Density, fibre stress, compressive strength and modulus of elasticity of clear wood, panel and structural timber products.
Young's Modulus (or Tensile Modulus alt. Modulus of Elasticity) and Ultimate Tensile Strength and Yield Strength for materials like steel, glass, wood and many more.
