Beauty and mystery—it is hard to imagine a more alluring combination, and this is precisely what we encounter when we observe phenomena in the nanoworld. But are we really sure that observations made ...

Electron spiral: phase of the beam near the tip of the needle Twisted beams of electrons have been used for the first time to determine the handedness, or “chirality”, of an ultrathin crystal. The new ...

Need a steel beam? You can 3D print PLA beams that are as strong as a steel beam of equivalent weight according to [RepRap]. The Python code for FreeCAD generates a repeating structure especially well ...

Researchers at The University of Manchester, Shandong Jiaotong University and Harbin Engineering University have developed a ...

In Chapters 9, 10 and 11 we investigated the strength of beams in terms of the stresses produced by the action of bending, shear and torsion, respectively. An associated problem is the determination ...

Beam clamps are devices that clamp onto a structural steel beam for support, lifting, and rigging applications. They connect components to the structural steel without drilling or welding, which could ...
