What is what part of the crossbow is used to draw the bow?

The part of the crossbow used to draw the bow is called the string. The user pulls back on the string, which bends the limbs of the crossbow and stores the energy needed to propel the arrow forward. The string is usually made of strong, flexible materials such as synthetic fibers or natural materials like animal sinew. The draw weight of the bow, or the amount of force required to pull back the string, can vary depending on the type of crossbow and the amount of power desired for shooting the arrow. Some crossbows may also have a cocking mechanism or a crank to assist in drawing the string back.
