a poor attempt ( now with fd curve )
sleek:
How much can hysteresis affect performance? Can it be enough to over come the benefits of added string tension? How do we measure hysteresis?
sleek:
Ok, I went back over my recurves with heat. I didnt add any more reflex, but put back what I lost with extra heat this time. My weight went up 4# to 44#@26. I also ploted the fd curve out to 26" of draw. Starting at 9 and going to 26" in pounds its 6, 10, 12, 14, 16.5, 18.5, 21, 23, 25, 27, 29, 30.5, 32, 34, 36.5, 38, 42, 44.
Now.... what do I do with this information? Specifically to calculate stored energy and efficiency?
sleek:
Im looking around this and thinking, wow, thats very linear. Probably not that geat a draw curve. I need more pre loading in the early draw. Need to get my string tension up.
Badger:
Sleek, to get all your numbers you have to shoot it through a chrono. You never know about hysterisis until you actually shoot it. Your bow is storing slightly less than 40# of energy at 26" which is not too bad for a 26" draw.
sleek:
Would the bow benefit from another two inches of draw? Or should I leave it be? You mentioned a sweet spot before and I dont know how you quantify that?
