25. The lateral load causes the nanobeam to exert an upward force on the cantilever-tip assembly. When this upward force exceeds the applied normal load, the tip passes over the nanobeam. The applied normal load can be varied in our experiments to control the degree to which the nanobeams are deflected.

27. The boundary conditions arey (x = 0) = y′ (x = 0) = 0 and y″ (x = L) = y′″ (x = L) = 0, where X = L corresponds to the end of the beam. Furthermore, the force P is only applied at the point a.

39. 2 substrate is atomically flat in the region where the force discontinuity is observed. Furthermore, the topographic signal, which was recorded at the same time as F, is constant across the region of force discontinuity.

42. The bending strength is relevant to composites formed with randomly oriented nanotubes or NRs. In a composite made with oriented nanotubes or NRs, the tensile and compressive strengths should also be considered. The tensile and bending strengths are comparable for SiC whiskers (6, 7) and are also expected to be similar for SiC NRs. The tensile strength of a carbon nanotube is, however, expected to be substantially larger than the nanotube bending strength and the strength of SiC NRs.
