WebThe mechanical theory featured in some of the earliest scientific discussions of the mechanism of adhesion, published by McBain and Hopkins in 1925, and still finds a place in contemporary accounts of theories of adhesion. At different times during the intervening period, quite different assessments of its significance have been made. WebParticles with a smoother surface will generally have a lower frictional interaction and flow more easily than those that are rougher, assuming all other features are identical. Mechanical Interlocking Particles of a certain shape can mechanically interlock and resist flow. Inter-particulate forces of cohesion
