Semester: SEM2
Originating Department: Civil Engineering
Pre-requisites: PHY002ORPHY004

 Aims To introduce basic principles of statics and to illustrate the application of these principles to the formulation and solution of a range of representative civil engineering problems.
 Learning outcomes A. Understand and apply the derivation of mathematical models for static analysis of mechanical systems.B. Analyse trusses and beam structures.C. Analyse beam cross sections, determination of centroids, moments of inertia, section modulus, principal axes and principal moments of inertia.D. Determine stresses corresponding to normal force and bending moments.E. Determine deflections in beams structures using Macaulay’s method of integration and moment-area method.F. Perform stress and strain transformations using method of equation and Mohr’s circle.
 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.
