Aims

• To build knowledge of the mechanics of dynamics and vibration, stress analysis of structures and sections, trusses and frames, and the mechanics of soils.

• Mechanics of Static Systems (Stress Analysis): Introduction to thin-walled and thick-walled cylinders; Thick-walled cylinders: Part yield and burst; Compound cylinders; Shear stresses in beams; Sheer centre of sections; Torsion of closed and open thin-walled sections.
• Mechanics of Static Systems (Trusses and Frames): Finite Element Method for two-dimensional trusses; Continuous beams.
• Mechanics of Satic Systems (Mechanics of Soils): Stresses in soils; Limit state concepts; Stress discontinuity and rotation of major stresses; Bearing capacity of vertically loaded strip footing.
• Laboratories and data analysis

Learning Outcomes

• At the end of the year the student should be able to demonstrate knowledge and understanding of the theory and application of engineering mechanics.
• AHEP4 Learning Outcomes: In order to satisfy Professional Engineering Institution (PEI) accreditation requirements the following Accreditation of Higher Education Programmes (AHEP4) Learning Outcomes are assessed within this module:
• M1. Apply a comprehensive knowledge of mathematics, statistics, natural science and engineering principles to the solution of complex problems (exam assessed).
• M2. Formulate and analyse complex problems to reach substantiated conclusions (exam assessed).
• M3. Select and apply appropriate computational and analytical techniques to model complex problems, discussing the limitations of the techniques employed (coursework assessed).
• M12. Use practical laboratory and workshop skills to investigate complex problems (coursework assessed).

• Selection and application of appropriate analysis techniques
• Use of matrix algebra for problems in structural systems under static and dynamic loads
• Observation and recording of experimental data
• Preparation of technical reports
• The competent and safe use of laboratory equipment

• Numerical skills
• Analytical skills
• Time and resource management

Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

• The courses in mechanics are covered in lectures which are reinforced by regular problem sheets leading to the required problem solving capability.
• The topics covered in this module are analytical by nature and are assessed most effectively by timed, written examination which enables each student to demonstrate an ability to analyse and solve new problems.
• Students complete a technical report on a topic in mechanics related to the laboratory programme.
• The laboratory programme also provides formative, hands-on experience in the subject area of mechanics.
• Students are encouraged to make use of staff 'Surgeries' (otherwise "Office Hours") to discuss any aspect of the module with teaching staff on a one-to-one basis. These are sign-up sessions available for up to one hour per week.
• As part of this module, students are required to complete the following Laboratory Classes: M21 Vibration of Single Degree of Freedom; M22 Statics of Beams and Trusses; M23 Stress Analysis.

Summative Assessment

Formative Assessment:

Formative assessment is provided by means of compulsory formative problem sheets and in-class feedback during compulsory Laboratory classes.

■ Attendance at all activities marked with this symbol will be monitored. Students who fail to attend these activities, or to complete the summative or formative assessment specified above, will be subject to the procedures defined in the University's General Regulation V, and may be required to leave the University
