RE: Does Kinetic Energy = Penetration?
<BLOCKQUOTE id=quote<font size=1 face='Verdana, Arial, Helvetica' id=quote>quote:<hr height=1 noshade id=quote>KE goes up with velocity, but I think penetration would be more curvlinear than linear. In otherwords, ALL else being the same as you add speed, you will start to see a progressive increase in penetration, not linear. <hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face='Verdana, Arial, Helvetica' size=2 id=quote>
I agree with you totally.
Lets examine this scenario as shaft weight is concerned and get opinions from the gallery:
A pine needle in a tornado will often reach speeds of over 200 mph. These 5 gr(if that) pine needles are driven into the bark of trees up to 2 inches deep in some cases. IF my math is correct(probably isn't) the pine needles would only be traveling around 293 fps(in the 200 mph example). That would give the pine needle a KE of 1 ft pound. The only thing the pine needle has going for it is speed. It seems to me that is natures way of telling us all to just lighten up. I also saw the same thing happen with a drinking straw one day.
How much of a role would it appear that momentum and KE play in this scenario? How much or a role does it appear that speed plays here? Would it be safe to say that speed was all it took to get the job done?
