The workings can be compared to a modern compound bow system.

A compound crossbow is a modern crossbow and is similar to a compound bow.

This limb stiffness makes the compound bow more energy efficient than other bows, but the limbs are too stiff to be drawn comfortably with a string attached directly to them.

Other types of compound bows use either ( one or both ) cam shaped or eccentrically mounted pulleys in order to provide a " let off ", such that the archer is not holding against the maximum draw weight of the bow while trying to aim.

At the bow and the stern builders were able to create hollow sections, or compound bends, at the waterline making the entry point very fine.

They are popular with compound bow hunters as it allows one piece of equipment to be carried in the field without encumbering the hunter's body.

A compound bow is a modern bow that uses a levering system, usually of cables and pulleys, to bend the limbs.

The limbs of a compound bow are much stiffer than those of a recurve bow or longbow.

This limb stiffness makes the compound bow more energy-efficient than other bows, in conjunction with the pulley / cams.

The 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.

The use of this levering system gives the compound bow a characteristic draw-force curve which rises to a peak weight and then " lets off " to a lower holding weight.

The compound bow is little-affected by changes in temperature and humidity and it gives superior accuracy, velocity, and distance in comparison to other bows.

The compound bow was first developed in 1966 by Holless Wilbur Allen in Missouri, and a US patent was granted in 1969.

The compound bow has become increasingly popular.

In the United States, the compound is the dominant form of bow.

The central riser of a compound bow is usually made of aluminium or magnesium alloy, and many are made of the aircraft-grade 6061 aluminium alloy.

This let-off enables the archer to accurately shoot a compound bow with a much higher peak draw weight than other bows ( see below ).

One manufacturer, Concept Archery, is known for producing a compound bow with 99 % let-off.

The compound bow operates with a very different weight profile, reaching its peak weight within the first few inches of the draw, and remaining more flat and constant until the end of the cycle where the cams " let-off " and allow a reduced holding weight.

This manipulation of the peak weight throughout the draw ( accomplished by the elliptical shape of the cams that change leverage and mechanical advantage ) is why compound bows store more energy and shoot faster than an equivalent peak weight recurve bow or longbow.

* When a compound bow is drawn, the limbs are pulled in toward each other, by the buss cables, unlike a longbow or recurve where the limbs flex in the direction of the bow string.

Evidence for this has been found in Sibudu Cave, South Africa and the compound glues used were made from plant gum and red ochre.

CamelCase ( or camel case ), also known as medial capitals or Pascal case, is the practice of writing words with some inner uppercase letters, such as compound words or phrases in which the elements are joined without spaces, while each element has a capital letter within the compound.

Italian " avere " and " essere " as auxiliaries for forming compound tenses are used similarly to French " avoir " and " être ", Spanish only retains " haber " and has done away with " ser " in forming compound tenses, which are no longer used in either Spanish or Portuguese.

Liberty and security of the person are taken as a " compound " concept-security of the person has not been subject to separate interpretation by the Court.

For example, the chemical compound n-hexane has the structural formula, which shows that it has 6 carbon atoms arranged in a chain, and 14 hydrogen atoms.

A compound which has two immiscible hydrophilic and hydrophobic parts within the same molecule, is called an amphiphilic molecule.

More specifically, a compound has to be stable or metastable at 25 ° C.

A mineral is an element or chemical compound that is normally crystalline and that has been formed as a result of geological processes.

This is due to the fact that a compound bow will accelerate an arrow more gently and linearly as the cam unwinds so flexing the arrow less, as compared to the explosive acceleration of an arrow from a recurve bow where the full power of the limbs is applied to the arrow as soon as the string is released.

The 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 a string is plucked, it has intermittent periodical contact with the bridge ; this intermittent grazing of the string and bridge is not a static process, as the points of contact will gradually shift, being a compound function of amplitude, the curvature of the bridge, and string tension.

As of March 23, 2010, all American Deluxe Precision Basses came with a N3 stacked-coil Jazz Bass pickup in the bridge position, a 21-fret tinted maple neck with compound rosewood or maple fingerboard with white or black pearloid dot markers, an active / passive toggle switch, a high-mass vintage bridge, Hipshot lightweight vintage tuners, a stealth retainer bar for the A string and a bold CBS-era headstock decal.
