  2. Mattydale lay - Wikipedia

    en.wikipedia.org/wiki/Mattydale_lay

    Minuteman load – A special load that allows the firefighters to pull a large section of the hose onto their shoulders and have it drop off (called "paying out") in an organized fashion as they advance towards the fire. [8] "S" load, more commonly known as the "triple-layer" load – The hose is folded three times before being loaded.

    Triple lay ("triple fold", "triple load") A method of loading preconnected attack line into a hose bed or crosslay, often facilitating rapid hose deployment in a pre-flaked configuration. Turnout gear The protective clothing worn by firefighters, made of a fire-resistant material such as Nomex or Aramid, and designed to shield against extreme heat.

  5. Loading arm - Wikipedia

    en.wikipedia.org/wiki/Loading_arm

    Bottom loading arms. Top loading arms are used to load or unload road or rail tankers.Loading or unloading is done through the manhole on the top of the tanker. Top loading arms can also be used for tight-fill, vapor recovery, marine and other applications when used with specially designed and engineered components, such as vapor plates, tapered hatch plugs, and inflatable hatch seals.

  6. Metal hose - Wikipedia

    en.wikipedia.org/wiki/Metal_hose

    A metal hose is a flexible metal line element. There are two basic types of metal hose that differ in their design and application: stripwound hoses and corrugated hoses. Stripwound hoses have a high mechanical strength (e.g. tensile strength and tear strength).

  7. Triple deck theory - Wikipedia

    en.wikipedia.org/wiki/Triple_deck_theory

    Triple deck theory is a theory that describes a three-layered boundary-layer structure when sufficiently large disturbances are present in the boundary layer. This theory is able to successfully explain the phenomenon of boundary layer separation, but it has found applications in many other flow setups as well, [1] including the scaling of the lower-branch instability of the Blasius flow, [2 ...

  8. Culvert - Wikipedia

    en.wikipedia.org/wiki/Culvert

    A culvert under the Vistula river levee and a street in Warsaw. Construction or installation at a culvert site generally results in disturbance of the site's soil, stream banks, or stream bed, and can result in the occurrence of unwanted problems such as scour holes or slumping of banks adjacent to the culvert structure.

  9. Space frame - Wikipedia

    en.wikipedia.org/wiki/Space_frame

    The roof of this industrial building is supported by a space frame structure. If a force is applied to the blue node and the red bar were not present, the resultant effect on the structure would depend entirely on the blue node's bending rigidity, i.e. to its resistance (or lack thereof) to bending; however, with the red bar in place, then assuming negligible bending rigidity of the blue node ...
