Forces at play during "Cutting"?
I'm involved in a debate over the broadheads (arrowheads using multiple razor-sharp metal blades) for bow hunters. I need a little help in the physics dept.
I'm arguing that the sharpness of a blade is less important than than the fact that there IS a cutting surface (of some kind) AND, more importantly, the force exerted by the cutting surface against whatever is being cut- in this case bone, flesh, etc.
The argument arose because a new company is claiming that their arrowheads using a relatively dull flexible wire will cut as effectively as the traditional 3 and 4-bladed broadheads. The designer of these new heads claims that physics says even a dull edge, given sufficient force and velocity will cut as well as, if not better than, a sharp blade. Is there any truth to this? Is there a specific law that would explain this claim?
Thanks, in advance, for any helpful relies I get.
