Table 3 Comparison of equations used to calculate stalk flexural stiffness, stalk bending strength and bending stress for the traditional method and the new approach derived in this study
From: The effect of plant weight on estimations of stalk lodging resistance
| Â | Traditional method | New approach |
|---|---|---|
Stalk flexural stiffness | \(\frac{{M_{ext} }}{\delta }\) | \(\frac{{M_{TOTAL} }}{\delta }\) |
Stalk bending strength | \({ \hbox{max} }\left( {M_{ext} } \right)\) | \({ \hbox{max} }\left( {M_{TOTAL} } \right)\) |
Bending stress | \(\frac{{M_{ext} \left( {h_{p} } \right)}}{{S\left( {h_{p} } \right)}}\) | \(\frac{{M_{TOTAL} \left( {h_{p} } \right)}}{{S\left( {h_{p} } \right)}}\) |
