A chain may consist of two or more links. Chains can be classified by their design, which can be dictated by their use: * Those designed for lifting, such as when used with a Hoist (device), hoist; for pulling; or for securing, such as with a bicycle lock, have links that are torus-shaped, which make the chain flexible in two dimensions (the fixed third dimension being a chain's length). Small chains serving as Jewellery chain, jewellery are a mostly decorative analogue of such types. * Those designed for transferring power in machines have links designed to mesh with the teeth of the sprockets of the machine, and are flexible in only one dimension.

Girder
A girder () is a Beam (structure), beam used in construction. It is the main horizontal support of a structure which supports smaller beams. Girders often have an I-beam cross section composed of two load-bearing ''flanges'' separated by a stabilizing ''web'', but may also have a box girder, box shape, Z shape, or other forms. Girders are commonly used to build bridges. A girt is a vertically aligned girder placed to resist shear loads. Small steel girders are Rolling (metalworking), rolled into shape. Larger girders (1 m/3 feet deep or more) are made as plate girders, welded or bolted together from separate pieces of steel plate. The Warren truss, Warren type girder replaces the solid web with an open latticework truss between the flanges. This arrangement combines strength with economy of materials, minimizing weight and thereby reducing loads and expense. Patented in 1848 by its designers James Warren (engineer), James Warren and Willoughby Theobald Monzani, its st ...

Union Army Balloon Corps
The Union Army Balloon Corps was a branch of the Union Army during the American Civil War, established by presidential appointee Thaddeus S. C. Lowe. It was organized as a civilian operation, which employed a group of prominent American aeronauts and seven specially built, gas-filled balloons to perform aerial reconnaissance on the Confederate States Army. Lowe was one of a few veteran balloonists who was working on an attempt to make a transatlantic crossing by balloon. His efforts were interrupted by the onset of the Civil War, which broke out one week before one of his most important test flights. Subsequently, he offered his aviation expertise to the development of an air-war mechanism through the use of aerostats for reconnaissance purposes. Lowe met with U.S. President Abraham Lincoln on 11 June 1861, and proposed a demonstration with his own balloon, the ''Enterprise'', from the lawn of the armory directly across the street from the White House.

Pergola
A pergola is most commonly used as an outdoor garden feature forming a shaded walkway, passageway, or sitting area of vertical posts or pillars that usually support crossbeams and a sturdy open lattice, often upon which woody vines are trained. The origin of the word is the Late Latin ''pergula'', referring to a projecting eave. It also may be an extension of a building or serve as protection for an open terrace or a link between pavilions. They are different from green tunnels, with a green tunnel being a type of road under a canopy of trees. Depending on the context, the terms "pergola", "bower", and "arbor" are often used interchangeably. An "arbor" is also regarded as being a wooden bench seat with a roof, usually enclosed by lattice panels forming a framework for climbing plants; in evangelical Christianity, brush arbor revivals occur under such structures. A pergola, on the other hand, is a much larger and more open structure. Normally, a pergola does not include ...
