term for putting an arrow in a bow?
nock
to load an arrow for shooting ("nocking" an arrow), the archer places an arrow across the middle of the bow with the bowstring in the arrow's nock. to shoot, the archer pulls back (draws) the arrow and the bowstring, which in turn flexes the bow limbs, storing elastic energy. typically while maintaining the draw, the archer sights along the arrow to aim it. finally the archer releases (looses) the arrow, allowing the limbs' stored potential energy to convert into kinetic energy, which is transmitted via the bowstring to the arrow, propelling it to fly forward with high velocity.
bow and arrow
less powerful bows require arrows with less dynamic spine. (spine is the stiffness of the arrow.) less powerful bows have less effect in deforming the arrow as it is accelerated (see "euler" buckling, case i) from the bow and the arrow must be "easier" to flex around the riser of the bow before settling to its path. conversely, powerful bows need stiffer arrows with more spine, as the bow will have a much greater bending effect on the arrow as it is accelerated. an arrow with too much dynamic spine for the bow will not flex and as the string comes closer to the bow stave, the arrow will be forced off to the side. too little dynamic spine will result in the arrow deforming too much and being propelled off to the other side of the target. in extreme cases, the arrow may break before it can accelerate, which can be a safety hazard.
