Compound Bow - Simple Machine Allows for Great Advantage

The compound bow was invented in the 1960s by American Engineer Holless Allen. At the time Allen created the bow, it was illegal to manufacture devices that were attached to bows. In addition, it was illegal to use them in competitions or when hunting. This prevented Allen's bow from being manufactured, but that was a good thing. Over the course of several years he realized the design was flawed. The way the Cheap Vikings Jerseys cables crossed at the center of the bow interfered with the flight path of the arrow. In 1967 Allen fixed this problem, and eventually the bow became manufactured in the United States and worldwide. Allen's bow became so successful that it has become a dominantly used bow in hunting and competitions throughout the United States and abroad.

The compound bow is similar to traditional longbows and recurve bows except for its design and materials. This modern bow uses a levering system composed of cables and pulleys. The limbs are stiffer Cheap Texans Jerseys which makes the bow more energy efficient. The bow's strings are attached to pulleys which have cables attached to the opposite limbs. When the strings are pulled back, the pulleys turn causing the cables to be pulled. This bends the limbs and allows them to store energy. Although the mechanics behind the bow may seem complicated, the bow is actually quite easy to use.

The compound bow offers many Cheap Chiefs Jerseys advantages to hunters and competitors. The bow is more energy efficient than longbows or recurve bows. Changes in temperature and humidity have little effect on the bow giving it superior accuracy, velocity, and distance compared to other bows. The bow's let off usually ranges from 65-80% but it can reach 99%. The configuration of the horizontal limb minimizes the amount of vibration the shooter feels when the arrow is released. The pulleys also control the acceleration of the arrow.

Despite its advantages, the compound bow does have some disadvantages. One major complaint users of the bow have is that it is hard to restring the bow on your own. In order for you to be able to restring the bow, you need a special clamp called Cheap Jaguars Jerseys a bow press. In order to use a bow press, you need professional training. You can also go to a specialty shop to restring your bow, but you will have to pay. In addition, the bow has a low holding weight. This makes the bow more sensitive to form faults when fully drawn.
