Archer Erika Jones shooting a compound bow at the 2013 Archery World Cup. The bow has the axle attaching the limb to cam mounted at the edge of the cam as opposed to the center. In modern archery, a compound bow is a bow that uses a levering system, usually of cables and pulleys, to bend the limbs. [1]
This limb stiffness makes the compound bow more energy-efficient than other bows, in conjunction with the pulley/cams. The typical compound bow has its string applied to pulleys (cams), and one or both of the pulleys have one or more cables attached to the opposite limb. When the string is drawn back, the string causes the pulleys to turn.
Less powerful bows require arrows with less dynamic spine. (Spine is the stiffness of the arrow. [14]) Less powerful bows have less effect in deforming the arrow as it is accelerated (see Euler buckling, case I) from the bow and the arrow must be "easier" to flex around the riser of the bow before settling to its path.
A field archer shooting freestyle recurve at 60 m (66 yards). Field archery involves shooting at targets of varying (and sometimes unmarked) distance, often in rough terrain. Three common types of rounds (in the NFAA) are the field, hunter, and animal. A round consists of 28 targets in two units of 14 (until the early 60's two rounds of 28 were ...
A bow draw in archery is the method or technique of pulling back the bowstring [1] to store energy for the bow to shoot an arrow. The most common method [citation needed] in modern target archery is the Mediterranean draw, which has long been the usual method in European archery.
let-off (measure) – The difference between a compound bow's holding weight and draw weight. Expressed as a percentage of the draw weight; for example, a bow with a draw weight of 70 lb and holding weight of 14 lb would have 80% let-off. limb-driven rest (equipment) – A drop-away rest that is mechanically linked to one of a compound bow's limbs.
Wind was pronounced dead on the scene by the coroner at 10:20 p.m. The sheriff’s office did not release the identity of the suspect but said the person is in custody for criminal charges ...
On compound bows, feathers may be a hindrance, and plastic vanes are a better solution. At the high speeds coming off a compound bow, plastic vanes with no curvature still allow the arrow to fly straight without tumbling. Also, noise is increased with feathers on these higher-powered bows, which can be a problem for hunters. [5]
