What is most important, technical info.
The most important thing for a hunting archer has to be the force of penetration, the force of the arrow at the target. AS long as we're talking technical data.I mean 50 or 60# doesn't matter if we...

A lot depends on the efficiency of the bow. Ultimately, the fps (or meters per second) or the distance per second is the key. However, my recommendation is to keep it simple and set a minimum bow...

All that info is for the highly tech guns, and I want to make a comparison energy to energy.That's why the hard, cold calculations. Perhaps Tim or Woodbear, our test and mathboys, can help me...

Well that idea ain't gonna work. I found "1 foot pounds-force = 1.355818 joules" and I think most trad bows fall into 30-50? foot pounds of KE. You gotta realize they envisioned the goal and then made...

A gun provides much more energy than a bow. It cannot be compared : cinetic energy works with the square of speed (speed*speed), so if you multiply the speed by 4, you have 4*4=16 times more energy.So...

Jakob,The last thing you want to do is present the KE numbers of primitive arrows to people used to dealing with the absurd Nordic big game limits on muzzle energy for firearms. In this comparison,...

Hin, Sumpitan makes some good points.It is important to remember that an arrow kills not with impact or kinetic energy, but by causing rapid blood loss, and/or double lung collapse. An arrow CAN kill...

Here's a quick comparison of the sectional density of a wooden arrow vs. rifle bullet:9mm / 32g arrow: 0.50g/mm2.308 /9.7g bullet: 0.20g/mm2The mid-weight arrow has 2.5 times greater sectional density...

I did a quick check on the internet, and found this page:www.chuckhawks.com/sd.htmSo the arrow in your calculation is at LEAST 1.5 times heavier/mm2 than the ones with biggest SD in use for hunting...

No you wouldn't include blades. If you did it would be like you were shooting a 1" dowel at them and that wouldn't calculate well.
View ArticleRe: What is most important, technical info.
No of course not blades. We are calculating surface. The surface of a blade is about 0.5mm thick and 25mm wide... so that is about 12.5squaremm, and 32grams/12.5mm2=2.56g/mm2 and that is high... but...

If you are really interested in arrow penetration, I would suggest you do an internet search on the Ashby report on arrow lethality.Dr. Ashby showed that the best indicator of arrow lethality on big...
