This is made specific in the following prerequisite learning objectives, you show to be able to:
    -
  1. Model, evaluate and reflect on validity of shape (only for cables), support reactions and section forces in statically determinate skeletal structures and cables using equilibrium relations and virtual work (only on beam structures), required for learning objective 2 and 2.
