Learning Outcomes
On completion of this course, the student will be able to:
 Describe and manipulate fundamental concepts of stress, strain, and deformation in members carrying axial, bending, shear, and torsional loads;
 Determine how statically determinate trusses and beams carry load; for beams using diagrams of bending moment and shear force, and evaluate the resulting elastic deflections of the beams;
 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; and
 Describe and manipulate relevant concepts of combined loadings and stress and strain transformation.
