Need an arrow recommendation for a Pearson Colt 62" 28# @ 28", I am drawing 29" so about 30ish#. What do you recommend for both an aluminum shaft and carbon shaft?
Well, the deflection for the material is the same, that is "static spine" is measured as deflection from a consistent span, either 26 or 28 inches depending on the standard. It is dynamic spine that changes with arrow length.For a given shaft, such as an 1816, how much does the deflection increase per inch of shaft beyond 28"?
Well, yes. But static spine is a standardized measurement of a material's flexibility. Static spine doesn't change with arrow length any more than the diameter of the arrow changes with arrow length. Static spine is used as part of a way to **estimate** how a an arrow will behave dynamically, under acceleration. It is dynamic spine that you really care about.
If you have an arrow of a given flexibility, static spine, there are two basic ways to increase the dynamic spine, similar to making it "more whippy". Put more weight on the tip and make it longer--or both.And only way to change dynamic spine is to change point weight?
Nope.And only way to change dynamic spine is to change point weight?
Static spine is a static measurement of flexibility. It is a static measurement of a material's property, like arrow diameter. Dynamic spine is how an arrow behaves under acceleration.What are the differences in static spine and dynamic spine?
The way archers measure dynamic spine is by testing how well their bow and arrow combination works, by shooting through paper to see if the arrow is traveling straight through or at an angle, buy shooting unfleched bare shaft arrows and seeing if they land straight in to the target or if they land pointing in an angle, left or right, or by comparing the grouping of bare shafts relative to fletched shafts.so static spine basically becomes dynamic spine once the arrow is in motion...or maybe static spine is the base or beginning point of a certain spine, then once the arrow is in motion it is then called dynamic spine. Can dynamic spine be measured then...seems as though only static spine can be measured.
