Notation

The following notation is used throughout the torsion topic, unless noted otherwise:

  • ... bimoment
  • ... sectorial moment of inertia
  • ... angle of rotation due to torsional moment
  • ... first derivative of with respect to the local X axis of the member
  • ... second derivative of with respect to the local X axis of the member
  • ... third derivative of with respect to the local X axis of the member
