Drag (physics)
In fluid dynamics, drag, sometimes referred to as fluid resistance, is a force acting opposite to the direction of motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers, two solid surfaces, or between a fluid and a solid surface. Drag forces tend to decrease fluid velocity relative to the solid object in the fluid's path. Unlike other resistive forces, drag force depends on velocity. Drag force is proportional to the relative velocity for low-speed flow and is proportional to the velocity squared for high-speed flow. This distinction between low and high-speed flow is measured by the Reynolds number. Drag is instantaneously related to vorticity dynamics through the Josephson-Anderson relation. Examples Examples of drag include: * Net force, Net Aerodynamic force, aerodynamic or Fluid dynamics, hydrodynamic force: Drag acting opposite to the direction of movement of a solid object such as cars, aircraft, and boat hulls. * Viscou ...

Drag (entertainment)
Drag is a performance of exaggerated femininity, masculinity, or other forms of gender expression, usually for entertainment purposes. Drag usually involves cross-dressing. A drag queen is someone (usually male) who performs femininely and a drag king is someone (usually female) who performs masculinely. Performances often involve comedy, social satire, and at times political commentary. The term may be used as a noun as in the expression ''in drag'' or as an adjective as in ''drag show''. __TOC__ Etymology The origin of the term ''drag'' is uncertain; it may date as far back as the Elizabethan era in England, where it was used to describe male actors playing female roles in theaters where cross-dressing was the norm. The first recorded use of ''drag'' in reference to actors dressed in women's clothing is from 1870. One suggested etymological root is 19th-century theater slang, from the sensation of long skirts trailing on the floor. Another possible origin is the Yiddish term ...

Fishing Reel
A fishing reel is a hand-crank (mechanism), cranked reel used in angling to wind and stow fishing line, typically mounted onto a fishing rod, but may also be used on compound bows or crossbows to retrieve tethered arrows when bowfishing. Modern recreational fishing reels usually have fittings aiding in casting (fishing), casting for distance and accuracy, as well as controlling the speed and tension of line retrieval to avoid line snap and fishing hook, hook dislodgement. Fishing reels are traditionally used for bass fishing in angling and fly casting, competitive casting. They are typically attached near the handle of a fishing rod, though some specialized reels with pressure sensors for immediate retrieval are equipped on downrigger systems which are mounted directly to an ocean-going sport boat's gunwales or transom (nautical), transoms and are used for "deep drop" and trolling (fishing), trolling. The earliest fishing reel was invented in China at least since the Song dynasty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drag (percussion)
In ''rudimental drumming'', a form of percussion music, a drum rudiment is one of a number of relatively small patterns which form the foundation for more extended and complex drumming patterns. The term "drum rudiment" is most closely associated with various forms of ''field drumming'', where the snare drum plays a prominent role. In this context "rudiment" means not only "basic", but also ''fundamental''. This tradition of drumming originates in military drumming and it is a central component of martial music. Definition Rudimental drumming has something of a flexible definition, even within drumming societies devoted to that form of drumming. RudimentalDrumming.com defines it as "the study of coordination." The Percussive Arts Society defines it as a particular method for learning the drums—beginning with rudiments, and gradually building up speed and complexity through practicing those rudiments. ''Camp Duty Update'' defines a drum rudiment as an excerpt from a mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drag And Drop
In computer graphical user interfaces, drag and drop is a pointing device gesture in which the user (computing), user selects a virtual object by "grabbing" it and dragging it to a different location or onto another virtual object. In general, it can be used to invoke many kinds of actions, or create various types of associations between two abstract objects. As a feature, drag-and-drop support is not found in all software, though it is sometimes a fast and easy-to-learn technique. However, it is not always clear to users that an item can be dragged and dropped, or what command is performed by the drag and drop, which can decrease usability. Actions The basic sequence involved in drag and drop is: * Move the pointer (computing WIMP), pointer to the object * Press, and hold down, the button on the computer mouse, mouse or other pointing device, to "grab" the object * "Drag" the object to the desired location by moving the pointer to this one * "Drop" the object by releasing th ...

Police Drag
Dredging is the excavation of material from a water environment. Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value. In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger. Usually the main objectives of dredging is to recover material of value, or to create a greater depth of water. Dredging systems can either be shore-based, brought to a location based on barges, or built into purpose-built vessels. Dredging can have environmental impacts: it can disturb marine sediments, creating dredge plumes which can lead to both short- and long-term water pollution, damage or destroy seabed ecosystems, and release legacy human-sourced toxins captured in the sediment. These ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drag (Austin, Texas)
''The Drag'' is a nickname for a portion of Guadalupe Street that runs along the western edge of the University of Texas campus in Austin, Texas. The Drag began as a strip of shops which provided vital resources to UT students. Bookstores, restaurants, and clothing stores fulfilled student needs. The proximity to campus, particularly the Main Building and the Union Building, added to the popularity of the street. Past and present buildings on the Drag include the Harry Ransom Humanities Research Center, Raul's, Captain Quackenbush's Intergalactic Espresso and Dessert Company, Record Exchange (later renamed Sound Exchange at the NW corner of 21st Street), Hastings Music and Video (directly across from the West Mall and Student Union), Bevo's Bookstore, Urban Outfitters (at the SW corner of 24th Street), Varsity Theater which became Tower Records, Kerbey Lane Cafe, The Bazaar, Texadelphia, Dobie Mall, Goodall Wooten private dormitory, the University Baptist Church, and the ...

Drag Harrow
A drag harrow, a type of spring-tooth harrow, is a largely outdated type of soil Tillage, cultivation Tool, implement that is used to smooth the ground as well as loosen it after it has been plowed and cultipacker, packed. It uses many flexible iron teeth usually arranged into three rows. It has no hydraulic functionality and has to be raised/adjusted with one or multiple manual levers. It is a largely outdated piece of farm equipment, having been replaced by more modern disc harrows and hydraulically operated field cultivators. Uses A drag harrow is used to loosen and even out soil after it has been plowed and packed. It pulls up large rocks which may then be picked up manually and put in the tractor's stone box to remove from the field. The drag harrow also kills some weeds that may be present, but it is not very efficient in doing so due to its highly flexible teeth, hence it is not one of its primary functions. In modern times The drag harrow is not often used in moder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grapnel Anchor
An anchor is a device, normally made of metal, used to secure a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin ', which itself comes from the Greek (). Anchors can either be temporary or permanent. Permanent anchors are used in the creation of a mooring, and are rarely moved; a specialist service is normally needed to move or maintain them. Vessels carry one or more temporary anchors, which may be of different designs and weights. A sea anchor is a drag device, not in contact with the seabed, used to minimize drift of a vessel relative to the water. A drogue is a drag device used to slow or help steer a vessel running before a storm in a following or overtaking sea, or when crossing a bar in a breaking sea. Anchoring Anchors achieve holding power either by "hooking" into the seabed, or weight, or a combination of the two. The weight of the anchor chain can be more than that of the anch ...

Drag Parachute
A drogue parachute, also called drag chute, is a parachute designed for deployment from a rapidly moving object. It can be used for various purposes, such as to decrease speed, to provide control and stability, as a pilot parachute to deploy a larger parachute or a combination of these. Vehicles that have used drogue parachutes include multistage parachutes, aircraft, and spacecraft recovery systems. The drogue parachute was invented by Russian professor and parachute specialist Gleb Kotelnikov in 1912, who also invented the knapsack parachute. The Soviet Union introduced its first aircraft fitted with drogue parachutes during the mid 1930s; use of the technology expanded during and after the Second World War. A large number of jet-powered aircraft have been furnished with drogue parachutes, including the Boeing B-52 Stratofortress strategic bomber and the Eurofighter Typhoon multirole aircraft; they were also commonly used within crewed space vehicle recovery programmes, ...
