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.

The compound bow has the string attached to the pulleys, one or both of which has one or more cables attached to the opposite limb.

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.

he wanted the mission compound to be effortlessly spotless.

The principal advantages of compound turbines are the reduction in size of any one casing, the confinement of the highest pressure to the smaller casing ( which may be made of stronger and more expensive materials ) and the possibility of divided flow in the low-pressure casing for the purpose of equalizing end thrusts.

Aliovalent substitutions change the overall charge within the ionic compound, but the ionic compound must be neutral.
