24. The theoretical models are also applicable to cantilever beams composed of crystalline materials, provided the crystal orientation is fixed over the length of the beam. The calibrated cantilevers satisfy this condition.

29. To establish the ultimate lower limit for LIb, for which the models are applicable, measurements need to he performed on cantilevers with aspect ratios smaller than those used in this study.
30. These measurements were obtained by directing the AFM laser beam, which is normally used to measure the deflection of the cantilever, onto the cantilever substrate. The reflected signal was then processed in an identical manner to that described in the Appendix,
