  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. 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]

  5. I-beam - Wikipedia

    en.wikipedia.org/wiki/I-beam

    The dimension of a wide-flange I-beam. In the United States, steel I-beams are commonly specified using the depth and weight of the beam. For example, a "W10x22" beam ...

  6. Parallel-strand lumber - Wikipedia

    en.wikipedia.org/wiki/Parallel-strand_lumber

    The product is manufactured as a 12-by-12-inch (300 mm × 300 mm) or 12-by-18-inch (300 mm × 460 mm) billet in a rectangular cross-section, which is then typically sawn and trimmed to smaller cross-sectional sizes. The beams are continuously formed, so the length of the beam is limited only to the maximum length that can be handled and ...

  7. Span (engineering) - Wikipedia

    en.wikipedia.org/wiki/Span_(engineering)

    In engineering, span is the distance between two adjacent structural supports (e.g., two piers) of a structural member (e.g., a beam). Span is measured in the horizontal direction either between the faces of the supports (clear span) or between the centers of the bearing surfaces (effective span): [1] A span can be closed by a solid beam or by ...

  8. Triple beam balance - Wikipedia

    en.wikipedia.org/wiki/Triple_beam_balance

    The difference in size of the beams indicates the difference in weights and reading scale that each beam measures. Typically, the reading scale of the middle beam reads in 100 gram increments, the far beam in 10 gram increments, and the front beam can read from 0 to 10 grams. [2] The triple beam balance can be used to measure mass directly from ...

  9. Beam (structure) - Wikipedia

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

    A beam of PSL lumber installed to replace a load-bearing wall. The primary tool for structural analysis of beams is the Euler–Bernoulli beam equation. This equation accurately describes the elastic behaviour of slender beams where the cross sectional dimensions are small compared to the length of the beam.
