  2. Slotted angle - Wikipedia

    en.wikipedia.org/wiki/Slotted_angle

    Slotted angle (also sometimes referred to as slotted angle iron) is a system of reusable metal strips used to construct shelving, frames, work benches, equipment stands and other structures. The name derives, first, from the use of elongated slots punched into the metal at uniform intervals to enable assembly of structures fixed with nuts and ...

    en.wikipedia.org/wiki/Corrugated_galvanised_iron

    Corrugated galvanised iron (CGI) or steel, colloquially corrugated iron (near universal), wriggly tin (taken from UK military slang), pailing (in Caribbean English), corrugated sheet metal (in North America), zinc (in Cyprus and Nigeria) or custom orb / corro sheet (Australia), is a building material composed of sheets of hot-dip galvanised ...

  4. Shear (sheet metal) - Wikipedia

    en.wikipedia.org/wiki/Shear_(sheet_metal)

    Setting the blade on an angle decreases the amount of force required, but increases the stroke. A 5-degree shear angle decreases the force by about 20% [citation needed]. The amount of energy used is still the same. The moving blade may also be inclined 0.5 to 2.5°, called the rake angle, to keep the material from becoming wedged between the ...

    Utilizing a large number of identical steel members rather that unique size or shape members also reduces cost. [10] Strength/weight ratio – Construction materials are commonly categorized by their strength to weight ratio—or specific strength, which is the strength of a material divided by its density. These ratios indicate how useful the ...

    AA-8000: used for electrical building wire in the U.S. per the National Electrical Code, replacing AA-1350. [1] Al–Li (2.45% lithium): aerospace applications, including the Space Shuttle; Alnico (nickel, cobalt): used for permanent magnets; Aluminium–Scandium ; Birmabright (magnesium, manganese): used in car bodies, mainly used by Land ...

  8. Strength of materials - Wikipedia

    en.wikipedia.org/wiki/Strength_of_materials

    The strength of materials is determined using various methods of calculating the stresses and strains in structural members, such as beams, columns, and shafts. The methods employed to predict the response of a structure under loading and its susceptibility to various failure modes takes into account the properties of the materials such as its yield strength, ultimate strength, Young's modulus ...

  9. Structural material - Wikipedia

    en.wikipedia.org/wiki/Structural_material

    Steel is used extremely widely in all types of structures, due to its relatively low cost, high strength-to-weight ratio and speed of construction. Steel is a ductile material, which will behave elastically until it reaches yield (point 2 on the stress–strain curve), when it becomes plastic and will fail in a ductile manner (large strains, or ...
