A wingback (WB) is an offensive backfield position in American football. A wingback or flexback lines up off the line of scrimmage, generally a step behind, and outside of, a tight end. [1] [2] It is a versatile position, as the wingback may be called upon to block, take a handoff, or run downfield for a pass. [1]
The H-back position is like that of the "wingback deep" position previously described in a version of the single wing formation, and here is shown behind a wingback to emphasize that, although more often the H-back and wingback, if there is one, are on opposite sides of the set. It is possible to say the abbreviation "HB" is already taken up by ...
The term "wing-back" itself is gradually falling out of use as there is less of a distinction with the full-back roles in the modern game, especially when used in a 4–3–3 or 4–2–3–1 formation. [32] [35] The wing-back role is one of the most physically demanding positions in modern football.
Radial (solid and colored lines) and circumferential roads (dashed and gray lines) in Metro Manila's road network. Axial – along the center of a round body, or the axis of rotation of a body; Radial – along a direction pointing along a radius from the center of an object, or perpendicular to a curved path.
The term chord is also applied to the width of wing flaps, ailerons and rudder on an aircraft. Many wings are not rectangular, so they have different chords at different positions. Usually, the chord length is greatest where the wing joins the aircraft's fuselage (called the root chord) and decreases along the wing toward the wing's tip (the ...
The head of the radius has a cylindrical form, and on its upper surface is a shallow cup or fovea for articulation with the capitulum of the humerus.The circumference of the head is smooth; it is broad medially where it articulates with the radial notch of the ulna, narrow in the rest of its extent, which is embraced by the annular ligament.
After identifying the size of ring needed, it is then placed on around the leg with the help from the ringing pliers. [17] In Australia, ring sizes range from 1 to 15, plus special sizes for birds whose leg shapes require special rings, such as parrots and pelicans. [18] A researcher uses a wing ruler to measure a Lincoln's sparrow wing.
In mechanical engineering, backlash, sometimes called lash, play, or slop, is a clearance or lost motion in a mechanism caused by gaps between the parts. It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence."
