2. 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

3. 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 ...

4. Beam diameter - Wikipedia

   en.wikipedia.org/wiki/Beam_diameter

   Before the advent of the CCD beam profiler, the beam width was estimated using the knife-edge technique: slice a laser beam with a razor and measure the power of the clipped beam as a function of the razor position. The measured curve is the integral of the marginal distribution, and starts at the total beam power and decreases monotonically to ...

9. 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 ...
