The only way to support the weight of this veneer across a wide opening is by providing a shelf angle on which the masonry bears. [1] The shelf angle, in turn, is attached to major elements of the building structure such as floor beams or structural columns. Shelf angles are in reality a horizontal expansion joint which allows growth of the ...
The most notable bridge failure due to gusset plates is the collapse of I-35W Mississippi River bridge in Minneapolis, Minnesota on August 1, 2007. Investigators found that the bridge had 16 under-designed gusset plates that fractured and ripped, and that the remaining gusset plates were properly designed and remained intact.

For use in retail stores, the EUR-6-pallet is half the size of the EUR-pallet, 600 mm × 800 mm (24 in × 31 in). [9] ISO standards have also been published for these Euro-pallet types. To accommodate EUR-pallets, there are derivative intermodal containers that are about 2 in (5 cm) wider—these are commonly known as "pallet-wide" containers ...
An angle plate is a work holding device used as a fixture in metalworking. Angle plates are used to hold workpieces square to the table during marking out operations. Adjustable angle plates are also available for workpieces that need to be inclined, usually towards a milling cutter .
There are several techniques used, but the most common modern method is "air bending". Here, the die has a sharper angle than the required bend (typically 85 degrees for a 90 degree bend) and the upper tool is precisely controlled in its stroke to push the metal down the required amount to bend it through 90 degrees.
An angle bracket or angle brace or angle cleat is an L-shaped fastener used to join two parts generally at a 90-degree angle. It is typically made of metal but it can also be made of wood or plastic. Angle brackets feature holes in them for screws. A typical example use of is a shelf bracket for mounting a shelf on a wall.
Angular diameter: the angle subtended by an object. The angular diameter, angular size, apparent diameter, or apparent size is an angular separation (in units of angle) describing how large a sphere or circle appears from a given point of view. In the vision sciences, it is called the visual angle, and in optics, it is the angular aperture (of ...
