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.
Drawing a bow, from a 1908 archery manual. A bow consists of a semi-rigid but elastic arc with a high-tensile bowstring joining the ends of the two limbs of the bow.An arrow is a projectile with a pointed tip and a long shaft with stabilizer fins towards the back, with a narrow notch at the very end to contact the bowstring.

Allen was born July 12, 1909, in Stilwell, Kansas.In the 1960s, he sawed the ends off a conventional recurve bow and then added pulleys to each end. [1] Allen experimented with a number of designs to apply for a patent on June 23, 1966, [2] and U.S. patent 3,486,495 was granted to him in December 1969.

The bows that were used during the rule of Genghis Khan were smaller than the modern Manchu-derived weapons used at most Naadam.Paintings as well as at least one surviving example of a 13th-century Mongol bow from Tsagaan-Khad demonstrate that the medieval Mongolian bows had smaller siyahs and much less prominent leather string bridges.
