Method of teaching and learning 
Lectures and tutorials are integrated, i.e. each lecture contains new theoretical topics, worked examples and opportunities for students to solve problems. Some lectures are used as pure tutorials. Coursework, which enable students to use the acquired knowledge in an integrated manner, are given in essential parts of the syllabus. Simple computer software for analysis of trusses and beams is an integrated part of the coursework. Simple practical laboratory experiments (measurement of modulus of elasticity and deflections of timber boards subjected to bending) are carried out by the students and a report is submitted.
Syllabus 
Review: Basic vector mechanics. Forces. Moment of a force about a point. Moment of a force about a line. Force couple. Invariance of the torque of a force couple. Equivalent force systems. Transfer of forces and moments from one point to another. Equilibrium of rigid bodies. Supports and reaction forces.


Trusses: Characteristics of trusses. Supports and reactions. Statically determinate trusses. Method of sections. Brief introduction to normal stresses, strains and elongations in truss members, Hooke’s Law, Young’s Modulus and various characteristics of simple constitutive relations.


Cross section analysis: Centroids. First moment of area. Moment of inertia. Section modulus. Composite cross sections. Principal axes. Principal moments of inertia.


Beam structures: Supports and reactions. Statically determinate beams. Normal force, shear force and moment diagrams. Normal stresses corresponding to pure normal force. Normal stresses corresponding to pure bending moment. Normal stresses corresponding to normal force and bending moments.
