Fig. 7. Angle of deflection of models of increasing EI at the highest
unidirectional flow speed. Values are means ± s.d., N=3.
Upright posture is 90°. Non-buoyant models deflect more than buoyant
models of the same EI as determined by Kruskall-Wallis non-parametric
analysis (H=33.56, d.f.=11, P<0.05). Extra buoyant models
deflect less than predicted by best-fit trend lines fit to data from models
that vary in EI.
