What is a crossbow?
crossbows are the current interpretation of a
very old concept: some evidence shows
tools similar to crossbows existed back in 5th
century BC. History of crossbow is beyond the
scope of this course, if you want to dig deeper
into crossbow history please refer to this web
page on Wikipedia:
Crossbows, originally developed as siege
weapons, are today considered, in most
countries, as sport tools (archery equipment).
Crossbows are used for recreational shooting and
crossbow is a very simple machine: basically a
bow mounted onto a stock that stores energy as
the string is pulled back. As the string reaches
full draw a retention mechanism holds the string
the operator to take aim of target, as a trigger
is pulled the retention mechanism releases the
string and the bow releases the energy stored
propelling the arrow.
crossbows, despite being similar in function and
basic components to their ancient counterpart,
make use of high technology materials and
benefit from innovations derived from archery
such as the compound technology.
crossbow can be divided into two categories:
recurve and compounds
