Summary of Content

A firm foundation is given in this module in the subject areas of mechanical engineering design and materials. These subjects doe not re-appear again in the host program as named subjects. The expertise gained here, however, will be used later as a component of design and casework studies .


The taught syllabus will cover the following areas: Solid Mechanics Force analysis applying static equilibrium, support reactions, pin jointed frames, method of sections, joint resolution, shear force and bending moment diagrams, centroids and second moment of areas for symmetrical sections, parallel axis theorem, direct stress and strain, bending stress. Mechanical Integrity: Integrity as a limiting criteria. Modes of material and component failure. Factor of safety. Yield, fatigue, fracture, buckling and creep. Strain energy and virtual work. Unit load method. Applications to building structures. Analysis of stress and strain. 2-D strain systems. Mohr Circle of stress and strain. Torsion of circular solid and hollow shafts. Combined bending torsion and axial loading. Applications to building services systems and components. The Design Process: Introduction to the design process for the solution of engineering systems and components. Design specifications. Design protection. Safety and economy of design. Fail-safe principles. Influence of strength to weight ratio. Aestetic and ergonomic factors. Sources of information. Atomic Structure and Bonding: Internal structure of atoms. Electrton orbital model. Bonding within compouds. Crystal lattices and defects. Mechanical Properties of Material: Main mechanical properties and methods used to quantify them. Tensile strength, toughtness, hardness and ductility. Materials Technology: Engineering alloys. Equilibrium phase diagrams for ferrous and non-ferrous materials of engineering significance. Thermal treatment to produce required properties. Surface hardening techniques. Corrosion. Corrosion prevention. Galvanising, cathodic protection, sacrifical protection, electroplating and anodising. Materials for Building Construction: Characteristics of steel, concrete, brick and timber. Building structural elements, including foundations. Factors affecting building design and construction.

Learning Outcomes

The Engineering Benchmarks A1,A2,A4,A5,B2,B3,B5,B7,C1,C2 and C3 as specified in the BEng Building Services Engineering Programme Specification Document apply to this module.On completion of this module the student should be able to:- Explain structural integrity as a limiting criteria related to modes of material and component failure by yielding, buckling, fatigue and creep. (A1,A2,B3)- Describe strain energy and virtual work and apply the unit load method to analyse forces and displacements in plane skeletal structures. (A2,B2,B5)- Analyse forces, stress and strain in engineering components; analyse strain gauge data, and use Mohr Circles. (A2,B3,B5,C1,C2,C3)- Explain the nature of fatigue failure and the factors affecting fatigue and describe the endurance limit of components under cyclic loading. (A2,B3)- Explain the formal design process to the design of simple engineering systems. (A4)- Describe the internal structure of atoms and molecules. (A1)- Describe the different types of crystals and the defects evident within them, and explain how these defects affect the mechanical properties of materials. (A1,A5,B3,C1,C2)- Select alloy steels and cast irons and the appropriate heat treatment for a particular application. (A5,B2,C3)- Explain the principles of corrosion prevention and select appropriate corrosion prevention techniques for particular applications. (A5,B3)- Specify materials for a range of engineering applications including building construction and thermal insulation. (A5,B2,C1)

Teaching / Learning Strategy

The strategy will involve a lecture programme with laboratory experimentation support, directed reading of books and handout notes, a tutorial programme of problem solving and instruction in module content with frequent reference to engineering applications. Learning and teaching strategies will be developed and implemented, appropriate to students' needs, to enable all students to participate fully in the programme.

Transferrable Skills

The Engineering Benchmarks D1,D2,D3 and D6 for transferable skills as specified in the BEng Building Services Engineering Programme Specification Document apply to this module. Students will enhance their ability to conduct analysis and use mathematics in the context of engineering problem solving. They should also develop the ability to apply empirical data to practical systems and appreciate the limitations of such data. (D1,D2,D3,D6)
