  2. Ship measurements - Wikipedia

    en.wikipedia.org/wiki/Ship_measurements

    Grain Cube (or Grain Capacity) – The maximum space available for cargo measured in cubic metres or feet, the measurement being taken to the inside of the shell plating of the ship or to the outside of the frames and to the top of the beam or underside of the deck plating. It is a measurement of capacity for cargoes such as grain, where the ...

  3. Beam (nautical) - Wikipedia

    en.wikipedia.org/wiki/Beam_(nautical)

    Graphical representation of the dimensions used to describe a ship. Dimension "b" is the beam at waterline.. The beam of a ship is its width at its widest point. The maximum beam (B MAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (B H) only includes permanently fixed parts of the hull, and beam at waterline (B WL) is the maximum width where the ...

  4. I-beam - Wikipedia

    en.wikipedia.org/wiki/I-beam

    where I is the moment of inertia of the beam cross-section and c is the distance of the top of the beam from the neutral axis (see beam theory for more details). For a beam of cross-sectional area a and height h , the ideal cross-section would have half the area at a distance ⁠ h / 2 ⁠ above the cross-section and the other half at a ...

  5. Beam diameter - Wikipedia

    en.wikipedia.org/wiki/Beam_diameter

    The D4σ width of a beam in the horizontal or vertical direction is 4 times σ, where σ is the standard deviation of the horizontal or vertical marginal distribution respectively. Mathematically, the D4σ beam width in the x dimension for the beam profile (,) is expressed as [3]

  6. Structural steel - Wikipedia

    en.wikipedia.org/wiki/Structural_steel

    Structural steel shapes, sizes, chemical composition, mechanical properties such as strengths, storage practices, etc., are regulated by standards in most industrialized countries. Most structural steel shapes, such as Ɪ-beams , have high second moments of area , which means they are very stiff in respect to their cross-sectional area and ...

  7. Hollow structural section - Wikipedia

    en.wikipedia.org/wiki/Hollow_structural_section

    (HSS dimensions are based on exterior dimensions of the profile; pipes are also manufactured to an exterior tolerance, albeit to a different standard.) The corners of HSS are heavily rounded, having a radius which is approximately twice the wall thickness. The wall thickness is uniform around the section.

  8. Lifting beam - Wikipedia

    en.wikipedia.org/wiki/Lifting_beam

    The lifting beam (also known as traverse, spreader beam) is a steel beam that is attached to the hook of the crane in order to spread the slings from one end of an elongated load (like a wall panel) to another. The bottom of the beam has multiple connection points for hanging the load. [1] H-shaped traverse

  9. DIN 1025 - Wikipedia

    en.wikipedia.org/wiki/DIN_1025

    DIN 1025 is a DIN standard which defines the dimensions, masses and sectional properties of hot rolled I-beams.. The standard is divided in 5 parts: DIN 1025-1: Hot rolled I-sections - Part 1: Narrow flange I-sections, I-serie - Dimensions, masses, sectional properties
