drag (redirected from dragged feet)

drag

Force exerted by a fluid stream on any obstacle in its path or felt by an object moving through a fluid. Its magnitude and how it may be reduced are important to designers of moving vehicles, ships, suspension bridges, cooling towers, and other structures. Drag forces are conventionally described by a drag coefficient, defined irrespective of the shape of the body. Dimensional analysis reveals that the drag coefficient depends on the Reynolds number; the precise dependence must be elucidated experimentally and can be used to predict the drag forces experienced by other bodies in other fluids at other velocities. Engineers use this principle of dynamic similarity when they apply results obtained with a model structure to predict the behaviour of other structures. See also friction; streamline.

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.

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

8. short for drag race

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.
