Archery

Archery is the art, practice, or skill of propelling arrows with the use of a bow, from Latin arcus. Historically, archery has been used for hunting and combat, while in modern times, its main use is that of a recreational activity. A person who participates in archery is typically known as an "archer" or "bowman", and one who is fond of or an expert at archery can be referred to as a "toxophilite".


 I first got interested in archery on a school trip to castle toward which allows pupils to take part in many outdoor activities such as hiking at night, abseiling and archery. When I came home I asked my dad if I could take up archery fortunately for me there was an archery class up at Atlantis every Friday night for beginners to experts. I have now been going to archery up at Atlantis  for 6 years now and I still enjoy it. I now have two bows a compound and a recurve.

 
 
There are many different types of bows such as Self bows, Laminated bows and Composite bows.These bows are directly drawn bows which means that they can be further divided based upon differences in the method of limb construction.

Bows can also be classified by the bow shape of the limbs when unstrung; in contrast to simple straight bows, a recurve bow has tips that curve away from the archer when the bow is unstrung.
The cross-section of the limb also varies; the classic longbow is a tall bow with narrow limbs that are D-shaped in cross section, and the flatbow has flat wide limbs that are approximately rectangular in cross-section. The classic D-shape comes from the use of the wood of the yew tree.  Cable-backed bows use cords as the back of the bow; the draw weight of the bow can be adjusted by changing the tension of the cable. They were widespread among Inuit who lacked easy access to good bow wood. One variety of cable-backed bow is the Penobscot bow or Wabenaki bow, invented by Frank Loring (Chief Big Thunder) about 1900.[19] It consists of a small bow attached by cables on the back of a larger main bow. Compound bows are designed to reduce the force required to hold the string at full draw, hence allowing the archer more time to aim with less muscular stress. Most compound designs use cams or elliptical wheels on the ends of the limbs to achieve this. A typical let-off is anywhere from 65%–80%. The compound bow was invented by Holless Wilbur Allen in the 1960s (a US patent was filed in 1966 and granted in 1969) and it has become the most widely used type of bow for all forms of archery in North America.


Mechanically drawn bows typically have a stock or other mounting, such as the crossbow. They are not limited by the strength of a single archer and larger varieties have been used as siege engines.
