Can I convert acalculated energy figure into approximate draw weight?

(1/3) > >>

stuckinthemud:
I have a lever bow. The levers reduce measured draw weight but I cannot get a string to stay tied to the end of the working section in order to measure the actual bow-weight.  I can find arrow weight and velocity which in turn gives me an energy figure.  How do I convert energy into draw weight?

Thanks in advance,
Andrew

bradsmith2010:
can you send pic,,and why wont string stay on,,

Badger:
 I f you tell us how much an arrow weighed and how fast it shot at what draw length we can give you a rough idea of your draw weight. You can look up KE conversion calculators on line. If you assume about 75% efficient you should be pretty close.

Badger:
 I am a bit confused as to why you can't measure the draw weight, can you elaborate on that a bit?

GlisGlis:
"The levers reduce measured draw weight"
The force on the string comes from working sections and levers combined
When you draw the string you are acting on the tips of the bow not where the working sections end
