Learning Outcomes
On completion of this course, the student will be able to:
- Describe the basic concepts of stress, strain and deformation in members carrying axial, bending and torsional loads;
- Determine how a statically determinate beam carries load using diagrams of bending moment and shear force, and evaluate the resulting elastic deflection of the beam;
- Analyse structural cross sections, so as to determine the elastic stress and strain distributions, as well as the deformations, resulting from axial, bending and torsional actions.
