  2. Structural channel - Wikipedia

    en.wikipedia.org/wiki/Structural_channel

    The structural channel is not used as much in construction as symmetrical beams, in part because its bending axis is not centered on the width of the flanges. If a load is applied equally across its top, the beam will tend to twist away from the web. This may not be a weak point or problem for a particular design, but is a factor to be ...

  3. Cellular beam - Wikipedia

    en.wikipedia.org/wiki/Cellular_beam

    Cellular beam is a further development of the traditional castellated beam. [1] The advantage of the steel beam castellation process is that it increases strength without adding weight, making both versions an inexpensive solution to achieve maximum structural load capacity in building construction .

  4. I-beam - Wikipedia

    en.wikipedia.org/wiki/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 is approximately 10 in (254 mm) in depth with a nominal height of the I-beam from the outer face of one flange to the outer face of the other flange, and weighs 22 lb/ft (33 kg/m).

    en.wikipedia.org/wiki/Beechcraft_RC-12_Guardrail

    The Beechcraft RC-12 Guardrail is an airborne signals intelligence (SIGINT) collection platform based on the Beechcraft King Air and Super King Air.While the US military and specifically the United States Army have numerous personnel transport variants of the King Air platforms referred to with the general C-12 designation, the RC-12 specification refers to a heavily modified platform that ...

  7. Ship measurements - Wikipedia

    en.wikipedia.org/wiki/Ship_measurements

    Lightweight displacement – LWD – The weight or mass of the ship excluding cargo, fuel, ballast, stores, passengers, and crew, but with water in the boilers to steaming level. Loadline displacement – The weight or mass of the ship loaded to the load line or plimsoll mark. Deadweight tonnage (DWT) is a measure of how much weight a ship can ...

  8. T-beam - Wikipedia

    en.wikipedia.org/wiki/T-beam

    Unlike an I-beam, a T-beam lacks a bottom flange, which carries savings in terms of materials, but at the loss of resistance to tensile forces. [5] T- beam designs come in many sizes, lengths and widths to suit where they are to be used (eg highway bridge, underground parking garage) and how they have to resist the tension, compression and shear stresses associated with beam bending in their ...

  9. Federal Bridge Gross Weight Formula - Wikipedia

    en.wikipedia.org/wiki/Federal_Bridge_Gross...

    CMVs are restricted by gross weight (total weight of vehicle and cargo), and by axle weight (i.e., the weight carried by each tire). The federal weight limits for CMVs are 80,000 pounds (36,000 kg) for gross weight (unless the bridge formula dictates a lower limit), 34,000 pounds (15,000 kg) for a tandem axle, and 20,000 pounds (9,100 kg) for a ...
