|Summary||This course engages students with the fundamental principles of Structural Mechanics relevant to civil and mechanical engineers. Specific topics including: equilibrium, stress, strain, axial load, torsion, bending, shear, and deflections in structural elements including beams, columns, struts, ties, and trusses.

- T4 Free Body Diagrams and Stress Resultants
Truss equilibrium. Stress resultants in struts (axial load), shafts (torsion), beams (shear and bending) and pressure vessels (membrane forces).
- T5 Members carrying Axial Load
Simple mechanical behaviour. Deformation (due to load and thermal strain).
- T6 Members carrying Torsion
Torsion of circular shafts and other closed sections. Torsional stiffness and deformation.

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;
- Describe and manipulate relevant concepts of combined loadings and stress and strain transformation.
