Subject Description

Unit 1, Mechanics of materials: On completion of this unit, students should be able to: understand elastic and inelastic behaviour; determine stresses and deformations in, common structural elements. Topics covered include: two dimensional stress and strain analysis, principal values, Mohr's circle, failure criteria; Basic properties of beams, symmetric bending; flexure by McAulay's method, superposition, indeterminacy; short and long columns, inelastic behaviour.

Unit 2, Dynamics of machines: On completion students should: understand how to perform kinematic and dynamic analysis of planar mechanisms using analytical, numerical and/or graphical methods; be proficient at identifying, modelling and analysing vibrating single degree of freedom systems. Topics covered include: structural analysis and synthesis; mobility, velocity and acceleration diagrams; analytical kinematics of planar mechanisms; forces in machine members; dynamic reactions in joints; dynamics of mechanism input links, equation of motion, balancing; equations of motion of undamped, damped, free and forced vibration, kinematic and dynamic excitation; natural frequency, critical speed, resonance, transfer functions; application of integral transforms; applications in machine design.

Assessment

Laboratory and tutorial work assignments not exceeding 20 pages equivalent; one examination not exceeding three hours. Students will be notified of the weighting of assessment components at the beginning of semester.
