SUMMARY:The planar elastica\, stress\, and material stress - James Hanna (
 Virginia Polytechnic Institute and State University)

DESCRIPTION:<span>   <span>We   revisit the classical problem of the plana
 r Euler \\emph{elastica} with   applied forces and moments\, and present a
  classification of the shapes in   terms of tangentially conserved quantit
 ies associated with spatial and   material symmetries.&nbsp\; We compare  
  commonly used director\, variational\, and dynamical systems representati
 ons\,   and present several illustrative physical examples.&nbsp\; <br>   
   We remark that an approach that employs only the shape equation for the 
   tangential angle obscures physical information about the tension in the 
 body.</span></span>
