Draw Lengths and Arrow Weights

<< < (3/4) > >>

Wyrda:
In regards to your question, I was just reading the Bowyers Bible series and came across a very interesting fact - the bow tillered to bend more in the middle will actually have a more acute string angle at full draw, and thus stack less and store more energy than a bow that bends more towards the tips. The most efficient bow designs all have stiff tips, and your theoretical design would likely not have the best performance. However, self bows are limited by how much they can bend in the handle as taking set in the handle has a far larger effect than set near the tips, which significantly robs performance. Interestingly, when we look at period art, the bows often have fine, lightweight and stiff tips. Clearly the medieval bowyers knew what they were doing.

Practical constraints like anchoring consistency and bow efficiency often favor 30" for archers of average height.

I dont know about anchoring consistency,  but I do know the longer the draw the more power an arrow can get from a bow.

jackylizz:
This mechanism is also easy to understand because pulling the bowstring longer usually means increasing the tension, thereby making the arrow fly further, stronger and more accurately.

Hey! First things First, WELCOME, glad you are here :)

A very interesting thing about pulling a bow string that is counter intuitive. The further you pull a string, the less stress there is on the string. A string has the highest tension at brace. This is because the bow has the most leverage over the string the less bent the bow is. As the bow is drawn, there is a transfer of mechanical advantages between the bow and the string, and the bows advantages decrease and the strings increase. That continues until the bow starts to stack and the advantages swap places again.
