Max... I only mess with R/D's A recurve is a different animal... My guess is that it would be a bit higher because at brace you are actually dealing with a shorter limb which could give you a bit more tension...
No string tension is determined by how much reflex the bow has unstrung. Recurve or longbow - it doesn't matter, just total reflex. It is only comparable one bow to the next at the same brace height. If you want more string tension then you should use more reflex. It is as simple as that.
It is more a byproduct of a good design rather than a specific thing to aim for on its own. [/b]
That argument implies that string tension is totally dependent on limb load. What you are saying is basically; "The further reflexed the limbs are the greater the load when braced thus the string tension must be higher."
But it fails to answer why when measured from a lower brace, thus the limbs are less loaded, does the tension go up instead of down?Does reflex (and thus limb load) play a part here? Yes, but the string angle affects how the limbs impart that load into the string.
The really cool thing is how string angle does one thing on draw, but something very different in cast. But that's a different story and a lot more math..
Shredd,
You got it buddy, recurves unlocked a couple things in archery when someone accidentally discovered them. One, you have compounded lengths at work as it gets longer as it is drawn. Two, the string angle is consistently lower throughout the draw as the string angle is never higher than the angle between the limb and the string at the point the string breaks contact with the limb.
In part, my reference here and in my initial response was TTBB vol. 1 chapter 3 wherein Tim Baker discusses the effects of various elements of bow design; my other reference is my love for physics which, like Honest Abe, never lies.
