RE: Let's discuss.....
The article you spoke about and the accomanying pictures was gross the guy was just lucky man.
As to your response, a question i would have is: Just how much does an arrow resist being pushed off the string (an object at rest tends to stay at rest), and how much stored energy does the flexing of the arrow release before it actually leaves the string? As an example ; If the arrow only moves 12 inches before it makes contact with an object at rest how much KE is expelled before it gets there. At three feet? at 6 feet? (as long as we are measuring in yards). If a 70# bow has a 65% letoff and the arrow has only moved 6 inches before is stikes an object, is the full force (Potential) of the arrows energy been achieved?
