Broadening and deepening of knowledge and understanding of mechanics (dynamics and control, mechanics of solids and stress analysis) from the base established in MEC1011, appropriate for a professional mechanical or manufacturing engineering career, or as a basis for further advanced level study of these topics.
Outline Of Syllabus
DYNAMICS AND CONTROL
2D rigid body dynamics and kinematics; pure translation; general plane motion; free body diagrams.
Free and forced vibrations of damped single degree of freedom system applications.
Concepts of control and feedback; first and second order systems; transfer functions and block diagrams; response to step and ramp inputs; analysis of steady state errors.
Dynamics and Control Laboratory and analytical assignments based on SIMULINK modelling software.
MECHANICS OF SOLIDS AND STRESS ANALYSIS
3D stress and strain, Mohr’s circle, principal stresses and other invariants, yield criteria; introduction to the finite element method (FEM) for stress analysis, with applications; introduction to contact mechanics, creepage, wear and fatigue crack growth; laboratory measurement of strain and beam deflection.

Teaching Rationale And Relationship
Lectures convey the underlying engineering science and the approaches required to apply this to the discipline-specific problems identified.
Tutorials support the students' self-study in reading around the lecture material and learning to solve the practical engineering problems posed by the Tutorial Questions.
Laboratory work enables students to attain hands-on experience in analysing and solving real engineering problems using software modelling tools.
Computer-based modelling assignments and reporting of these develop essential professional engineering skills in this field.
The format of resits will be determined by the Board of Examiners
|Practical/lab report||1||M||5||Strength of materials laboratory report (max 10 hours).|
|Report||2||M||15||Finite Element Application assignment (max 10 hours).|
|Report||2||M||5||Simulink Control simulation assignment.|
Assessment Rationale And Relationship
The examination provides an appropriate way to assess both theoretical understanding and practical problem solving skills under time-constraint as required in industry.
Laboratory work enables more realistic engineering problems to be set and may also assess data acquisition and software skills. The students will be aware of the definitions, SI units and dimensions of physical quantities and be able to apply the broad base of scientific principles, which underpin the characteristics and uses of engineering discipline, with some deeper knowledge and understanding in a chosen topic.
The software simulation and analysis assignments cover essential professional skills that cannot be assessed realistically in an examination.
For the purposes of professional body accreditation, in order to obtain a passing mark overall for this module (40%) at the first attempt the minimum acceptable mark for each of the assessment items specified below shall be 30%, with the maximum possible module overall mark where this is not the case being restricted to 35% (Undergraduate Progress Regulations):
(1) 75% Exams (Sem 1 & 2)
(2) 25% Laboratory Practical and Design Assignments (FEA & control).
