  2. Specific strength - Wikipedia

    en.wikipedia.org/wiki/Specific_strength

    It is also known as the strength-to-weight ratio or strength/weight ratio or strength-to-mass ratio. In fiber or textile applications, tenacity is the usual measure of specific strength. The SI unit for specific strength is Pa ⋅ m 3 / kg , or N ⋅m/kg, which is dimensionally equivalent to m 2 /s 2 , though the latter form is rarely used.

  3. Barbell - Wikipedia

    en.wikipedia.org/wiki/Barbell

    Stating that bar should weigh 25 kg (55 lb) with collars on, effectively permits use of 20 kg (44 lb) bars only, because same as IWF, [3] IPF requires collars to weigh 2.5 kg (5.5 lb) each. [6] The total weight of the barbell varies based on the type and number of plates loaded onto the ends of the bar and the lift being performed, and easily ...

  4. 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 ...

    en.wikipedia.org/wiki/Linear_density

    pound (mass) per yard: used in the North American railway industry for the linear density of rails; pound (mass) per foot; pound (mass) per inch; tex, a unit of measure for the linear density of fibers, defined as the mass in grams per 1,000 meters; denier, a unit of measure for the linear density of fibers, defined as the mass in grams per ...

  6. Digging bar - Wikipedia

    en.wikipedia.org/wiki/Digging_bar

    Chisel — a sharpened blade for cutting roots, digging and prying. A pinch point bar has a chisel at one end. Bars are typically 5 to 6 ft (1.5 to 1.8 m) long and weigh 15 to 23 lb (6.8 to 10.4 kg). They are usually made entirely of cylindrical or hexagonal forged steel with a diameter of approximately 1 in (2.5 cm).

  7. Rebar - Wikipedia

    en.wikipedia.org/wiki/Rebar

    Rebar (short for reinforcement bar or reinforcing bar), known when massed as reinforcing steel or steel reinforcement, [1] is a tension device added to concrete to form reinforced concrete and reinforced masonry structures to strengthen and aid the concrete under tension.
