Figure 4-16. The variation in an applied force on a probe (solid line) that exactly balances
that from a Mie force (dotted line) between a probe tip and a surface as a function of tip
position. The net force is zero such that stable equilibrium positions of the tip are possible
for all imposed probe positions. The values are normalized using the characteristic values
( Eqs. 4-22 and 4-25 ).
Figure 4-17. Indentation and adhesive interactions between a probe and a surface plotted
in contact mechanics coordinates for which forces and displacements are taken as
positive directed into the surface. The relationship between these coordinates and those of
Fig. 4-16 is given by Eqs. 4-31 and 4-32 .
