crossbows.

crossbows have been around for many centuries and have had a lot of different designs. The crossbow was invented around 500 B.C in Greece. the basic design of a crossbow is that it is a bow mounted to a handle and is shot horizontally. The cross bow can produce much more power (trust) to propel the arrow because it is mounted and the user does not have to hold the weight like a regular bow, he can simple draw the string back and it is caulked and loaded ready to fire when pressing the trigger. the modern crossbows have pulleys on them to ease the draw weight. Many crossbows today have a fiberglass limb, fiberglass has great characteristics of flexibility and strength. In modern cross bow we switched from metal to fiberglass for those reasons and metal under constant stress will wear out and lose its utility after a while. there are tones of different designs but my favorite is the modern crossbows because it has the best of all the designs and will last a long time. this is a picture of the medieval crossbow

and here is a modern design with fiberglass limbs.
