In 1967, Holles Wilbur Allen invented the compound bow in Missouri. This bow make use of cables and pulleys that form a leverage system in order to bend the limbs as well as the ends of the bow. Keep in mind that the long bow, also called the recurve bow, always has limbs that are more flexible as compared to the compound bow. The stores for the compound bow have more energy as compared to most other bows but results in stiff limbs. Virtually, it is impossible to pull the bow back using a single string. This issue will be solved with the use of both the pulleys and cables. As you can see, the string is attached to a certain pulley attached with a cable to the opposite limb. Afterwards, the pulley will turn as soon as the string is being pulled back. The pulley pulls the cable that bends the limbs. At the end of the day, the stored energy will be very ready to send a flying arrow.
Compound Bow Advantages
Resistance to endure temperature changes is one of the advantages of a compound bow. As a result the speed and accuracy of the arrow and how far the arrow will travel makes compound bow more effective as compared to the standard long compound bow parts.
Compound Bow Strength
What delivers these traditional archery bows added strength is the pulleys and cables and the make up of the limbs and shafts. The major shaft of the compound bows are called the riser, and they are composed of either aluminum or magnesium; both lightweight and strong materials. As a matter of fact, the highest quality performing compound bows are made of the highest aircraft quality aluminum. So why do people use this kind of material? The answer would be to keep the rise as unbending as possible. You wish the riser to be stiff so you can add pieces of equipment to bow such as sights, quivers, or stabilizers.
The cables and strings are made of polyethylene and must be strong enough at the same time very much flexible since they need to stretch out when the bow is drawn. Due to its flexibility, it then moves the energy from the bow up to the arrow as soon as the string is release as a result in maximum distance. On the other hand, the cables are made of steel surround by a clear plastic.
