  3. Properties of concrete - Wikipedia

    en.wikipedia.org/wiki/Properties_of_concrete

    The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1] Reinforced concrete is the most common form of concrete. The reinforcement is often steel rebar (mesh, spiral, bars and other forms). Structural fibers of various materials are available.

    It is property per unit width, per unit mass of reinforcement. For example, UNIT STRENGTH is defined as load in Newton per millimeter (of laminate width) for a layer consisting of 1 kg of glass per square meter. i.e. the unit is N/mm per Kg/m2 glass

  5. Sectional density - Wikipedia

    en.wikipedia.org/wiki/Sectional_density

    The SI derived unit for sectional density is kilograms per square meter (kg/m 2). The general formula with units then becomes: / = where: SD kg/m 2 is the sectional density in kilograms per square meters; m kg is the weight of the object in kilograms; A m 2 is the cross sectional area of the object in meters

  6. Specific modulus - Wikipedia

    en.wikipedia.org/wiki/Specific_modulus

    Specific modulus is a materials property consisting of the elastic modulus per mass density of a material. It is also known as the stiffness to weight ratio or specific stiffness. High specific modulus materials find wide application in aerospace applications where minimum structural weight is required.

    With Prescott out for the season, let's be realistic about the moves the Cowboys need to (and can) make. Also, Aaron Rodgers raises eyebrows within the Jets, the week's best throws, and much more.

  9. Specific weight - Wikipedia

    en.wikipedia.org/wiki/Specific_weight

    The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...
