Stanchion
A stanchion () is a sturdy upright fixture that provides support for some other object. It can be a permanent fixture. Types In architecture, stanchions are the upright iron bars in windows that pass through the eyes of the saddle bars or horizontal irons to steady the leadlight. The French call the latter ''traverses'', the stanchions ''montants'', and the whole arrangement ''armature''. Stanchions frequently finish with ornamental heads forged out of the iron. Stanchions are also the metal supporting members of lighting mounted from a lower elevation. This includes the metal inclined member for mounting a streetlight to a telephone or power pole, and the dedicated metal vertical support of a self-supporting or bottom-fed streetlight. In this case, the stanchion pole may double as the Electrical conduit, raceway for the electrical feed to the lighting. In industrial installations, walkway lighting may be mounted with a stanchion that is secured to a hand-rail. Stanchion lights ...

Bollard
A bollard is a sturdy, short, vertical post. The term originally referred to a post on a ship or quay used principally for mooring boats. In modern usage, it also refers to posts installed to control road traffic and posts designed to prevent automotive vehicles from colliding with pedestrians and structures. Etymology The term is probably related to bole, meaning a tree trunk. The earliest citation given by the ''Oxford English Dictionary'' (referring to a maritime bollard) dates from 1844, although a reference in the '' Caledonian Mercury'' in 1817 describes bollards as huge posts. History Wooden posts were used for basic traffic management from at least the second half of the 17th century. One early well-documented case is that of the "postes and rales in ye King's highway for ye (safety) of all foot passengers" erected in 1671 in the High Street of Old Brentford, Middlesex (part of the London–Bath road). Another is that of "two oak-posts" set up next to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Rope
Red is the color at the long wavelength end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–750 nanometres. It is a primary color in the RGB color model and a secondary color (made from magenta and yellow) in the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. Red pigment made from ochre was one of the first colors used in prehistoric art. The Ancient Egyptians and Mayans colored their faces red in ceremonies; Roman generals had their bodies colored red to celebrate victories. It was also an important color in China, where it was used to color early pottery and later the gates and walls of palaces. In the Renaissance, the brilliant red costumes for the nobility and wealthy were dyed with kermes and cochineal. The 19th century brought the ...

Yacht
A yacht () is a sail- or marine propulsion, motor-propelled watercraft made for pleasure, cruising, or racing. There is no standard definition, though the term generally applies to vessels with a cabin intended for overnight use. To be termed a , as opposed to a , such a pleasure vessel is likely to be at least in length and may have been judged to have good aesthetic qualities. The Commercial Yacht Code classifies yachts and over as . Such yachts typically require a hired crew and have higher construction standards. Further classifications for large yachts are : carrying no more than 12 passengers; : solely for the pleasure of the owner and guests, or by Flag#At sea, flag, the country under which it is registered. A superyacht (sometimes ) generally refers to any yacht (sail or power) longer than . Racing yachts are designed to emphasize performance over comfort. Charter yachts are run as a business for profit. As of 2020, there were more than 15,000 yachts of sufficient size ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pillar (car)
The pillars on a car with permanent roof body style (such as four-door sedans) are the vertical or nearly vertical supports of its window area or greenhouse—designated respectively as the A, B, C and (in larger cars such as 4-door station wagons and sport utility vehicles) D-pillar, moving from front to rear, in profile view. Nomenclature Car pillars are vertical or inclined components of an enclosed automobile's body that both support its roof and reinforce the torsional rigidity of the body. An alphabetical convention for designating a car's pillars has developed over time, used variously by the automotive press in describing and reviewing vehicles, insurance companies in identifying damaged components, and first-responder rescue teams to facilitate communication, as when using the jaws of life to cut their way into a wreck. The letters A, B, C, and D are used (in upper case): * The A-pillar is the forward-most pillar on a vehicle, supporting its roof at each corner ...

Ice Hockey
Ice hockey (or simply hockey in North America) is a team sport played on ice skates, usually on an Ice rink, ice skating rink with Ice hockey rink, lines and markings specific to the sport. It belongs to a family of sports called hockey. Two opposing teams use ice hockey sticks to control, advance, and Shot (ice hockey), shoot a vulcanized rubber hockey puck into the other team's net. Each Goal (ice hockey), goal is worth one point. The team with the highest score after an hour of playing time is declared the winner; ties are broken in Overtime (ice hockey), overtime or a Shootout (ice hockey), shootout. In a formal game, each team has six Ice skating, skaters on the ice at a time, barring any penalties, including a goaltender. It is a contact sport#Grades, full contact game and one of the more physically demanding team sports. The modern sport of ice hockey was developed in Canada, most notably in Montreal, where the first indoor ice hockey game, first indoor game was play ...

River Rafting
A river is a natural stream of fresh water that flows on land or inside caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth. Water first enters rivers through precipitation, whether from rainfall, the runoff of water down a slope, the melting of glaciers or snow, or seepage from aquifers beneath the surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins, or catchments, areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their banks and flood the surrounding area, spreading nutrients to the surrounding area. Sediment or alluvium carried by rivers shapes the landscape ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Fork
A bicycle fork is the part of a bicycle that holds the front wheel. A fork typically consists of two ''blades'' which are joined at the top by a fork ''crown.'' The crown is often at the front. Most suspension forks have an arch connecting the two side of the lowers (the part connected to the axle.) It is often in front of the stanchions (shaft the lowers slide on) but not always. Above the crown, a ''steerer tube'' attaches the fork to the bicycle and the Bicycle handlebar, handlebars (via a Stem (bike), stem) allowing the rider to steer the bicycle. The steerer tube of the fork interfaces with the Bicycle frame, frame via Bearing (mechanical), bearings called a headset (bicycle part), headset mounted in the head tube. At the bottom of the fork, ''fork ends'' hold the wheel. Usually, either the axle is bolted to the fork, or a ''quick release skewer'' passes through a hollow axle, clamping the axle to the fork. A bicycle dropout (drop out, frame end, or fork end), is a slot in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dairy Farming
Dairy farming is a class of agriculture for the long-term production of milk, which is processed (either on the farm or at a dairy plant, either of which may be called a dairy) for the eventual sale of a dairy product. Dairy farming has a history that goes back to the early Neolithic era, around the seventh millennium BC, in many regions of Europe and Africa. Before the 20th century, milking was done by hand on small farms. Beginning in the early 20th century, milking was done in large scale dairy farms with innovations including rotary parlors, the milking pipeline, and automatic milking systems that were commercially developed in the early 1990s. Milk preservation methods have improved starting with the arrival of refrigeration technology in the late 19th century, which included direct expansion refrigeration and the plate heat exchanger. These cooling methods allowed dairy farms to preserve milk by reducing spoiling due to bacterial growth and humidity. Worldwide, le ...

Standing Passenger
In urban public transport, provision is made for standing passengers, often called straphangers or standees, to rationalize operation and to provide extra capacity during rush hour. On crowded rapid transit urban lines, while most travelers may be seated during off-peak services, only a limited proportion will be seated during the peak services. The longer the journey, the less willing passengers are to stand. On intercity rail or coach services, the willingness among passengers to stand is often low, or it may even be prohibited, with reserved seating to ensure that all passengers can be seated. Furthermore, there are also modes of public transport where standing is always prohibited in the vehicle, including school buses, gondola lifts, and amusement park railways. In aviation, safety measures require all passengers and crew to be seated with their seat belts fastened during taxiing, take-off, landing, and turbulence, so airlines do not allow passengers to travel without a ...

Cargo Aircraft
A cargo aircraft (also known as freight aircraft, freighter, airlifter or cargo jet) is a fixed-wing aircraft that is designed or converted for the carriage of cargo rather than passengers. Such aircraft generally feature one or more large doors for loading cargo. Passenger amenities are removed or not installed, although there are usually basic comfort facilities for the crew such as a galley, lavatory, and bunks in larger planes. Freighters may be operated by civil passenger or cargo airlines, by private individuals, or by government agencies of individual countries such as the armed forces. Aircraft designed for cargo flight usually have features that distinguish them from conventional passenger aircraft: a wide/tall fuselage cross-section, a high-wing to allow the cargo area to sit near the ground, numerous wheels to allow it to land at unprepared locations, and a high-mounted tail to allow cargo to be driven directly into and off the aircraft. By 2015, dedicated freighter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Aircraft
A military aircraft is any Fixed-wing aircraft, fixed-wing or rotorcraft, rotary-wing aircraft that is operated by a legal or insurrectionary military of any type. Some military aircraft engage directly in aerial warfare, while others take on support roles: * Combat aircraft, such as Fighter aircraft, fighters and Bomber, bombers, are designed to destroy enemy equipment or personnel using their own aircraft ordnance, ordnance. Combat aircraft are typically developed and procured only by military forces. * Non-combat aircraft, such as military transport aircraft, transports and Tanker (aircraft), tankers, are not designed for combat as their primary function but may carry weapons for self-defense. These mainly operate in support roles, and may be developed by either military forces or civilian organizations. History Lighter-than-air In 1783, when the first practical aircraft (hot-air and hydrogen balloons) were established, they were quickly adopted for military duties. The ...
