drag

1. an implement, such as a dragnet, dredge, etc., used for dragging
2. a sporting coach with seats inside and out, usually drawn by four horses
3. a braking or retarding device, such as a metal piece fitted to the underside of the wheel of a horse-drawn vehicle
4. Aeronautics the resistance to the motion of a body passing through a fluid, esp through air: applied to an aircraft in flight, it is the component of the resultant aerodynamic force measured parallel to the direction of air flow
5. the trail of scent left by a fox or other animal hunted with hounds
6. an artificial trail of a strong-smelling substance, sometimes including aniseed, drawn over the ground for hounds to follow
7. Angling unnatural movement imparted to a fly, esp a dry fly, by tension on the angler's line

drag

[drag]
(computer science)
To move an object across a screen by moving a pointing device while holding down the control button.
(engineering)
A tool fashioned from sheet steel and having a toothed edge along the long dimension; used to level and scratch plaster to produce a key for the next coat of plaster. Also known as comb.
A tool consisting of a steel plate with a finely serrated edge; dragged over the surface to dress stone.
(fluid mechanics)
Resistance caused by friction in the direction opposite to that of the motion of the center of gravity of a moving body in a fluid.
(metallurgy)
The bottom part of a flask used in casting.
In thermal cutting, the distance deviating from the theoretical vertical line of cutting measured along the bottom surface of the material.
(mining engineering)
Movement of the hanging wall with respect to the foot wall due to the weight of the arch block in an inclined slope.

1. A piece of sheet steel with a toothed edge along the long dimension; used to level and scratch plaster to produce a key for the next coat; a comb.
2. A tool consisting of a steel plate having a finely serrated edge; used to dress stone by dragging it back and forth across the surface.

drag
i. That component of aerodynamic forces acting on the wing or the airfoil section, which is parallel and opposite to the relative airflow. The sources of drag are the pressure distribution patterns over the airfoil, called induced drag; the skin friction of the surface; and other factors like the shape of the airfoil. Total drag is the sum total of induced drag and parasite drag. Drag (D) = Coefficient of drag (CD) x ¼ density (ρ) x square of relative speed (V2) x surface area (S); or D = CDqS, where D is the drag, q the dynamic pressure (¼ρV2), and S the surface area.
ii. The fore-and-aft movement of the tips of the blade of a helicopter rotor in its plane of rotation. The freedom given to each blade of a rotor to allow it to move in the plane of rotation independently of other blades. This is to avoid bending stress at the root. The blade is allowed to lead or lag about a dragging hinge, but movement of the hinge is restricted by some form of drag damper to avoid undesirable oscillations.

drag

To move an object on screen such that its complete movement is visible from starting location to destination. The movement may be activated with a stylus, mouse or keyboard keys.

To drag an object with the mouse, point to it. Press the mouse button and hold the button down while moving the mouse. When the object is at its new location, release the mouse button. See Win Drag and drop.
