According to the invention, the reflector is capable of occupying at least one first angular position in which the beam emitted thereby passes through a first glass to generate a first type of beam, and a second angular position which is fixed and different form the first angular position(s)...
So, it’s good to have an idea of the different types of steel beams to better understand when and why a structural engineer will choose one beam type over another. First, let’s take a look at how steel beams are made. How are steel beams made? There are two primary ways to fabric...
this type of bridge started being used extensively with the arrival of metalworks, steel boxes, and pre-stressed construction concrete. Beam bridges today are separated into girder bridges, plate girder bridges, box girder bridges, and simple
a laser printer is a type of printer that uses a laser beam and powdered toner to produce text and images on paper. it is commonly found in offices and businesses due to its fast-printing speeds and high-quality output. how does a laser printer work? laser printers use a laser beam to...
When heavier, load-bearing beams are exposed in the interior of the space, the natural wood provides visual variation from the rest of the room. In cases where load-bearing beams are not required, a copy of the beam is created using plywood and miters – and is used simply for its aesth...

This paper extends the previous applications of the combination technique of axisymmetric solid and solid elements for three dimensional stress analysis to several other types of element combinations, such as, plate-solid, axisymmetric plate-axisymmetric solid and beam-plane stress elements. Without using...
