- TL;DR Summary
- I would like feedback on the anatomy of an arrow from a physics point of view
I have studied arrows and arrow flight the best I can for a number of years owning an archery shop
A number of years ago I began testing arrows in the shop which we refer to as a static test
We look at straightness, deflection matching and weight matching
We also test to find the stiffest point and index that point to the same orientation
It is believed that by finding the stiffest point the arrows will flex 90 degrees from that point during flight
Now we also believe arrows have two axis points, the front point is called the centre of mass, the rear the centre of drag
My question is how can I find the front axis
Some in archery feel you can pinch the arrow between two fingers then tap the arrow on a hard surface and then pay attention to the vibration in the shaft. Moving the pinch left and right a little at a time until you find the location of the longest vibration
So if anyone could help with this I'm all ears
