Fig. 8. Effective elastic modulus (Eeff) during deformation of
isolated setal arrays. Horizontal labels denote direction of deformation
relative to the curvature of the setae. Values are means ± s.e.m.
Letters A,B denote significant ANOVA contrasts. Dotted line shows
Eeff=100 kPa, the upper limit of Dahlquist's criterion for
tack (Dahlquist, 1969;
Pocius, 2002).
