Alpha is often used in physics and chemistry as a symbol or in the names of things, for example alpha particles (which are two protons and two neutrons bound together into a particle the same as a helium nucleus). The symbol is also used a lot in mathematics in algebra, for example naming angles.
Recurve bow. A recurve bow is a bow with limbs that curve away from the archer when unstrung. A recurve bow stores more energy and delivers energy more efficiently than the equivalent straight-limbed bow, giving a greater amount of energy and speed to the arrow.
Recurve risers and limbs - how to combine (self.Archery) submitted 4 years ago by. You build a takedown recurve with a combination of riser and limbs. However, you can use a long riser and short limbs, or short riser and long limbs, giving you two bows of the same overall length. I suspect that they will shoot differently. For a given bow length, is there a preferred way to combine the riser and limb length?
