ENG08032 2019 Mechanics of Machines
The purpose of this module to give students an understanding of fundamental mechanics and dynamics principles in order to make them aware of the forces present in the operation of high volume automated packaging and assembly machinery and also to make them aware of the effect of these forces in terms of machine deflection, vibration or component failure.
Learning Outcomes
On completion of this module the learner will/should be able to;
Solve beam deflection for a combination of concentrated and distributed loads.
Solve bending and torsion problems where loads cause plastic behaviour.
Calculate stresses using strain rosette data for parts under complex loading.
Solve problems involving linear and rotatory motion.
Solve problems involving dynamic balancing.
Construct computer simulated solutions to stress analysis and mechanism problems.
Teaching and Learning Strategies
Teaching and learning will take place through lectures on the theoretical material and practicals involving the computer simulations.
Fulltime
The theoretical and background material will be presented through a series of lectures. Application of the theory will be demonstrated in class, supported by computer simulations.
Online
This module will be delivered using blended learning techniques. The theoretical and background material will be presented through a series of online lectures. Application of the theory will be supported by computer simulations..
Module Assessment Strategies
Continuous assessment (20%)
Final exam (80%)
Repeat Assessments
Repeat assessment will involve sitting a final exam and/or resubmission of assignments.
Indicative Syllabus
- Deflection and stiffness : slope and deflection of beams using standard equations and Macaulay's method for general load cases.
- Elastic plastic behaviour : elastic/plastic bending & torsion, residual stresses, spring-back.
- Complex stresses and strains : strain-stress relationship in bi-axial loading, plane stress/plane strain, complex strains, analytical solutions of strain gauges measurements.
- Review of dynamics fundamentals : Newton’s laws, equations of linear and angular rotation.
- Dynamics of rotation : moment of inertia, parallel and perpendicular axis theorems, acceleration of geared systems, combined linear/rotational movement.
- Static and dynamic balancing : masses in single plane, masses in several transverse planes.
- Mathematical modelling and simulation of mechanisms : e.g., scotch yoke, slider crank, universal joint, etc.

Theory of Machines and Mechanisms covers the fundamentals of mechanisms, kinematics, and dynamics of machines. Known for its simplicity and clarity of writing style, the revised fourth edition features more worked examples throughout, new and updated end-of-chapter homework problems, and new information on synthesis and curvature theory. With a collection of MATLAB examples designed to tie the material in with MATLAB software and an in-text CD featuring working model animations of key concepts from the book, this is an ideal resource for students studying mechanical engineering.
