  2. Strut channel - Wikipedia

    en.wikipedia.org/wiki/Strut_channel

    Cross section diagram of standard strut channel. Basic strut channel comes in the open box section 1 + 5 ⁄ 8 in (41 mm) square. A half height 1 + 5 ⁄ 8 in × 13 ⁄ 16 in (41 mm × 21 mm) version is also available, used mostly where mounted directly to a wall as it has significantly less stiffness and ability to carry loads across an open space or brace.

  3. T-slot structural framing - Wikipedia

    en.wikipedia.org/wiki/T-slot_structural_framing

    T-slot structural framing is a framing system consisting of lengths of square or rectangular extruded aluminium, typically 6105-T5 aluminium alloy, with a T-slot down the centerline of one or more sides. It is also known under several generic names, such as aluminium extrusion, aluminium profile and 2020 extrusion if the cross-section is 20x20 ...

  4. Torsion bar suspension - Wikipedia

    en.wikipedia.org/wiki/Torsion_bar_suspension

    Torsion bar suspension. Schematic of a front axle highlighted to show torsion bar. A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever ...

  5. Open web steel joist - Wikipedia

    en.wikipedia.org/wiki/Open_web_steel_joist

    In structural engineering, the open web steel joist (OWSJ) is a lightweight steel truss consisting, in the standard form, of parallel chords and a triangulated web system, proportioned to span between bearing points. The main function of an OWSJ is to provide direct support for roof or floor deck and to transfer the load imposed on the deck to ...

  6. Strut - Wikipedia

    en.wikipedia.org/wiki/Strut

    Architecture and construction. Strut is a common name in timber framing for a support or brace of scantlings lighter than a post. Frequently struts are found in roof framing from either a tie beam or a king post to a principal rafter. Struts may be vertically plumb or leaning (then called canted, raking, or angled) and may be straight or curved.

  7. Lattice girder - Wikipedia

    en.wikipedia.org/wiki/Lattice_girder

    The term is also sometimes used to refer to a laced strut[2] or laced tie, structural members commonly made using a combination of structural sections connected with diagonal lacing. This form allows a strut to resist axial compression and a (tie) to resist axial tension. A lattice girder, like any girder, primarily resists bending.

  9. Bracing (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Bracing_(aeronautics)

    Bracing (aeronautics) In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of struts, which act in compression or tension as the need arises, and/or wires, which act only in ...
