<p>This is just a single closed form equation, which rivals and competes with the cumbersome 5 dimensional integrals of the theory of Persson and Scaraggi [2014] which is sold commercially (see <a href="http://www.multiscaleconsulting.com/">http://www.multiscaleconsulting.com/</a>) for a high price, and is not public domain.</p>
<p> </p>
<p>This single line equation explains the very sophisticated data of Pastewka and Robbins [2014] on PNAS, about pull-off, despite contrasts with the conclusion of Pastewka and Robbins that stickiness should depend only on rms slopes and rms curvatures. Indeed, in the BAM theory, pull-off depends only on rms amplitude of roughness!</p>
