Aims

Broadening and deepening of knowledge and understanding of mechanics (statics, dynamics and control, mechanics of solids and stress analysis) from the base established in MECHANICS I, appropriate for a professional engineering career, or as a basis for further advanced level study of these topics. The module has a strong mathematical bias and delivers fundamental theory behind many common engineering practices.

Outline Of Syllabus

The syllabus is structured around three main areas:

1.       Statics:

•       Concepts of static determinacy/indeterminacy and mechanisms for trusses, beams and frames;
•       Beams: loading, bending moment (BM), shear force (SF), BM and SF diagrams, differential equations for BM and SF;
•       Frames: loading, bending moment (BM), axial force (AF), shear force (SF) and BM, AF and SF diagrams;
•       Deflections using energy methods: energy balance, virtual work, Castiliano and Maxwell’s principle, Betti’s Law;
•       Analysis of statically indeterminate structures by the force method: trusses, beams and frames.

2.       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.

3.       Mechanics of solids and stress analysis:

•       3D stress and strain, Mohr’s circle, principal stresses and other invariants, yield criteria;
•       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. 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.

Computer-based modelling assignment and reporting develops essential professional engineering skills in this field.

Assessment Methods

The format of resits will be determined by the Board of Examiners
