Sometimes additional rungs are stretched between the two beams. A pair of trestle legs can support one or several boards or planks, forming a trestle table or trestle desk. A network of trestle supports can serve as the framework for a trestle bridge, and a trestle of appropriate size to hold wood for sawing is known as a sawhorse.
Greek τρισκελής (triskelḗs) means ' three-legged ' [4] from τρι-(tri-), ' three times ' [5] and σκέλος (skelos), ' leg '. [6] While the Greek adjective τρισκελής ' three-legged ' (e.g. of a table) is ancient, use of the term for the symbol is modern, introduced in 1835 by Honoré Théodoric d'Albert de Luynes as ...
The term "girder" is typically used to refer to a steel beam. In a beam or girder bridge, the beams themselves are the primary support for the deck, and are responsible for transferring the load down to the foundation. Material type, shape, and weight all affect how much weight a beam can hold.
Stirrup sample. Stirrups form the outer part of a rebar cage. The function of stirrups (often referred to as 'reinforcing steel links' and 'shear links') is threefold: to give the main reinforcement bars structure, to maintain a correct level of concrete cover, and to maintain an equal transferance of force throughout the supporting elements.

Inexpensive stirrups may be made of nickel, which can easily bend or break. Stirrups may also be made of synthetic materials and various metallic alloys. There are many variations on the standard stirrup design, most claiming either to be safer in the event of a fall or to make it easier for a rider to maintain a proper foot and leg position.
In a simpler construction, a shearleg derrick can be assembled from two posts to form A-frame shear legs without any crossbar. The bottom of the legs are set in two holes on the ground, spreading them apart. There is a rope to tie the two legs together near the bottom to prevent them from spreading apart further.
There really is nothing better than walking into a store that has a pet. That is, unless you aren't prepared to pay the "scratch tax." Thankfully, the woman was ready the day she walked into the ...
Key: 1: principal rafters, 2: collar beam, 3: arch braces. Lacking a tie beam, [ 11 ] the arch-braced (arched brace) [ 12 ] truss gives a more open look to the interior of the roof. The principal rafters are linked by a collar beam supported by a pair of arch braces, which stiffen the structure and help to transmit the weight of the roof down ...
