<p>[QUOTE=&quot;Leadfoot, post: 975645, member: 2972&quot;]To the contrary, I acknowldeged this point in post #42:</p><p><br /></p><p><br /></p><p><br /></p><p>The underlying point is this:&nbsp; A planchet isn&#039;t a perfect solid, its a malleable metal being struck by another harder metal (e.g. deformable body) so the formulas overestimate pressure.&nbsp; But not NEARLY enough to overcome the fact that the pressure increases linearly with the inverse of area. </p><p><br /></p><p>To use our example above, so maybe it&#039;s not 200psi, but rather 180 or 150 -- still more than 100psi!</p><p><br /></p><p>The point still stands.
