The first ever job of the Homo sapiens, (obviously us) is to kill almost everything that moves and scurry the ground. Humans cannot survive without protein, (our ancestors didn’t know what protein was before) and so they had devised so many tactics how to kill and eat.
During the stone-age, for 3.4 millions of years, everything was widely done with the use of an edged, pointed or percussion surfaced stone. For millions of years, our ancestral hunters majorly rely on a “missile” they had that has the weight to destroy when thrown, be it heavy bones, big stones or large minerals.
The “throwing trend” stopped 3000 years ago, somewhere in Africa when the primates discovered the earliest weapon ever, bows and arrows.
How does an arrow work?
When an arrow is released by the archer, the straight wooden killing machine will experience as what we call as “cast” (refers to the arrows speed and distance). The greater the archer has casted his weapon, the greater power the arrow has, its speed, distance, momentum is excellent.
Forceful arrows spend little time in the air. It will take a straight and direct route towards the target and will be less diverted by external factors such as wind and atmospheric conditions. The cast has fueled up the arrow transferring the Archers energy directly to the pointed wood. However in a cross sectional arena, a faintly heavier arrow will shoot through the air better considering the distance of the target, the longer the distance the more force you imply. It must be balance.
A bow provides momentum to the Archery supplies, (momentum means: weight x speed), in lay man’s term, a fully drawn bow will effectively transfer its force to an arrow but the arrows momentum will depend on its weight, if the arrow is too heavy, it will only shoot a few meters, if its light, it will shoot far but not stable.
How Arrows are made
Arrows came from rods or tubes of rigid, low density materials such as wood, carbon fibre, glass, aluminum or a composite fibre strategically covered by aluminum tubing.
Arrows must be stiff but still has a critical bend; a perfectly stiff arrow is impossible to shoot from a bow, and so having the right degree of bend in an arrow is one of its key features.
The best and still unbeatable material used for an arrow is carbon fibre bonded over an aluminum tubing.
Aluminum is weaker and heavier than carbon, which means that the overall diameter can be thicker (less aerodynamic) and the arrow heavier (slower) for a given stiffness, you can use aluminum depending on the desired result of the user, but usually Carbon is greater.
For a specific arrow weight, the tubes must have large openings and thin walls in order to achieve the desired stiffness yet on the down side they also are weaker than narrow thick walled tubes, so there must be balance or trade off. Tubular shaft are more preferred in making an arrow because a tube is more rigid than a solid rod.
