A significant part of bow tuning is vertical adjustment that strives for a zero angle of attack of the arrow. This requires laborious procedures through a lengthy and tedious trial and error phase. A mechanical and mathematical model of bow and arrow geometry in the vertical plane in braced and drawn situations has been constructed and investigated. An asymmetrical scheme, rigid beams, concentrated elastic elements, and non-stretchable string are the main features of the model. Numerical results of the computer simulation are presented in tabular and graphical form. This facilitates the use of the methods by archers and coaches.
