A-frame Level
An A-frame is a basic structure designed to bear a load in a lightweight economical manner. The simplest form of an A-frame is two similarly sized beams, arranged in an angle of 45 degrees or less, attached at the top, like an uppercase letter 'A'. These materials are often wooden or steel beams attached at the top by rope, welding, gluing, or riveting. A-frames can be used as-is, as part of shears, or set up in a row along a longitudinal beam for added stability, as in a saw horse. More complex structures will often have crossmembers connecting the A-frames at different angles,"A-frame" (2009). ''Oxford English Dictionary'' Second Edition on CD-ROM (v. 4.0).

Tent
A tent () is a shelter consisting of sheets of fabric or other material draped over, attached to a frame of poles or a supporting rope. While smaller tents may be free-standing or attached to the ground, large tents are usually anchored using guy ropes tied to stakes or tent pegs. First used as portable homes by nomads, tents are now more often used for recreational camping and as temporary shelters. Tents range in size from " bivouac" structures, just big enough for one person to sleep in, up to huge circus tents capable of seating thousands of people. Tents for recreational camping fall into two categories. Tents intended to be carried by backpackers are the smallest and lightest type. Small tents may be sufficiently light that they can be carried for long distances on a touring bicycle, a boat, or when backpacking. The second type are larger, heavier tents which are usually carried in a car or other vehicle. Depending on tent size and the experience of the person or people in ...

London Eye
The London Eye, or the Millennium Wheel, is a cantilevered observation wheel on the South Bank of the River Thames in London. It is Europe's tallest cantilevered observation wheel, and is the most popular paid tourist attraction in the United Kingdom with over 3 million visitors annually. It has made many appearances in popular culture. The structure is tall and the wheel has a diameter of . When it opened to the public in 2000 it was the world's tallest Ferris wheel. Its height was surpassed by the Star of Nanchang in 2006, the Singapore Flyer in 2008, and the High Roller (Las Vegas) in 2014. Supported by an A-frame on one side only, unlike the taller Nanchang and Singapore wheels, the Eye is described by its operators as "the world's tallest cantilevered observation wheel". The London Eye used to offer the highest public viewing point in London until it was superseded by the observation deck on the 72nd floor of The Shard, which opened to the public on 1 February ...

Whataburger
Whataburger is an American regional fast food restaurant chain, headquartered and based in San Antonio, Texas, that specializes in hamburgers. The company, founded by Harmon Dobson and Paul Burton, opened its first restaurant in Corpus Christi, Texas, in 1950. Family-owned by the Dobsons until 2019, the chain is now managed by a private equity firm along with the Dobson family still holding a small stake. There are more than 670 stores in Texas and over 150 in New Mexico, Arizona, Colorado, and the southern United States, of which 126 are franchised. Whataburger was known for many years for its distinct A-framed orange-and-white-stripe-roofed buildings ( a maroon stripe is added in College Station). The first A-frame restaurant was built in Odessa, Texas, in 1961 and was the 24th Whataburger to open and was a historical landmark. The site was demolished in 2019 and a new building was built. The company's focus is on ground beef burgers, and include the "Whataburger", the ...

Wienerschnitzel
Wienerschnitzel is an American fast food chain founded in 1961 (as "Der Wienerschnitzel") that specializes in hot dogs. Despite the name, the company does not sell Wiener schnitzel, only selling it once as a promotional item. Wienerschnitzel locations are found predominantly in California and Texas, though others are located in Arizona, Colorado, Illinois, Louisiana, New Mexico, Nevada, Utah, and Washington. Outside the 50 states, there is a store located in Guam and one in Panama. The chain is recognizable by the A-frame-style roofs of its older restaurants, similar to the original structures used by IHOP, Tastee-Freez, Nickerson Farms, and Whataburger. Structures that have been converted from Wienerschnitzels into other restaurants often retain the distinctive architecture. The chain's advertising mascot is an anthropomorphized hot dog known as The Delicious One, who runs from people who want to eat him. Wienerschnitzel sponsors the tongue-in-cheek Wiener Nationals, the '' ...

Disney's Contemporary Resort
Disney's Contemporary Resort, originally to be named Tempo Bay Hotel and previously the Contemporary Resort Hotel, is a resort located at the Walt Disney World Resort in Bay Lake, Florida. Opened on October 1, 1971, the hotel is one of two original properties located at the complex alongside Disney's Polynesian Village Resort, and is currently listed as a deluxe-priced resort. It is adjacent to the Magic Kingdom theme park, and is identified by its A-frame main building. History The Contemporary Resort is one of two resorts located on property when Walt Disney World opened in 1971. The Contemporary Tower, the most prominent of the resort's three stand-alone buildings, was built as an A-frame with outer walls which slope inwards around an inner atrium. This design was a collaboration by Disney, the United States Steel Corporation, and Xerox Tower architect Welton Becket. To construct the building, steel frames were erected on-site and modular pre-constructed rooms, designed by ...

Plumb Line
A plumb bob, plumb bob level, or plummet, is a weight, usually with a pointed tip on the bottom, suspended from a string and used as a vertical reference line, or plumb-line. It is a precursor to the spirit level and used to establish a vertical datum. It is typically made of stone, wood, or lead, but can also be made of other metals. If it is used for decoration, it may be made of bone or ivory. The instrument has been used since at least the time of ancient EgyptDenys A. Stocks. Experiments in Egyptian archaeology: stoneworking technology in ncient Egypt'. Routledge; 2003. . p. 180. to ensure that constructions are "plumb", or vertical. It is also used in surveying, to establish the nadir with respect to gravity of a point in space. It is used with a variety of instruments (including levels, theodolites, and steel tapes) to set the instrument exactly over a fixed survey marker or to transcribe positions onto the ground for placing a marker. Etymology The ''plu ...

Swing Bridge
A swing bridge (or swing span bridge) is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot. In its closed position, a swing bridge carrying a road or railway over a river or canal, for example, allows traffic to cross. When a water vessel needs to pass the bridge, road traffic is stopped (usually by traffic signals and barriers), and then motors rotate the bridge horizontally about its pivot point. The typical swing bridge will rotate approximately 90 degrees, or one-quarter turn; however, a bridge which intersects the navigation channel at an oblique angle may be built to rotate only 45 degrees, or ...

Suspension Bridge
A suspension bridge is a type of bridge in which the deck (bridge), deck is hung below suspension wire rope, cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world. Besides the bridge type most commonly called suspension bridges, covered in this article, there are other types of suspension bridges. The type covered here has cables suspended between towers, with vertical ''suspender cables'' that transfer the Structural load#Live load, imposed loads, transient load, live and Structural load#Dead load, dead loads of the deck below, upon which traffic crosses. This arrangement allows the deck to be level or to arc upward for additional clearance. Like other suspension bridge types, this type often is constructed without the use of falsework. The suspension cables must be anchored at each end of the bridge, s ...

Double Wishbone Suspension
A double wishbone suspension is an independent suspension design for automobiles using two (occasionally parallel) wishbone-shaped arms to locate the wheel. Each wishbone or arm has two mounting points to the chassis and one joint at the knuckle. The shock absorber and coil spring mount to the wishbones to control vertical movement. Double wishbone designs allow the engineer to carefully control the motion of the wheel throughout suspension travel, controlling such parameters as camber angle, caster angle, toe pattern, roll center height, scrub radius, scuff and more. Implementation The double-wishbone suspension can also be referred to as "double A-arms", though the arms themselves can be A-shaped, L-shaped, or even a single bar linkage. A single wishbone or A-arm can also be used in various other suspension types, such as variations of the MacPherson strut. The upper arm is usually shorter to induce negative camber as the suspension jounces (rises), and often this arrangement ...

Ladder
A ladder is a vertical or inclined set of rungs or steps used for climbing or descending. There are two types: rigid ladders that are self-supporting or that may be leaned against a vertical surface such as a wall, and rollable ladders, such as those made of rope or aluminium, that may be hung from the top. The vertical members of a rigid ladder are called stringers or rails (US) or stiles (UK). Rigid ladders are usually portable, but some types are permanently fixed to a structure, building, or equipment. They are commonly made of metal, wood, or fiberglass, but they have been known to be made of tough plastic. Historical usages Ladders are ancient tools and technology. A ladder is featured in a Mesolithic rock painting that is at least 10,000 years old, depicted in the Spider Caves in Valencia, Spain. The painting depicts two humans using a ladder to reach a wild honeybee nest to harvest honey. The ladder is depicted as long and flexible, possibly made out of some sort of gr ...
