Fig. 5. Comparison of uniform-safety-factor hypothesis versus actual
findings in the equine MC3. (A) Cross-section of the MC3 showing equivalent
safety factors as proposed by the uniform-safety-factor hypothesis. (B)
Cross-section of the MC3 based on present data showing large variations in
regional yield safety factors. Values shown are based on
`strain-mode-specific' testing [i.e. tension testing (T) of the habitually
tensed cranio-lateral cortex and compression testing (C) of the habitually
compressed caudo-medial cortex]. N.A., neutral axis.
