Aims:
The aim of this module is to develop core technical knowledge and understanding of the intimate relationship between mechanical engineering design (form and function), manufacturing methods and materials selection.

Learning Teaching & Assessment Strategy:
Key concepts will be developed in lectures and tutorials and practised in laboratory and individual project work. Learning outcomes LO 1.1, 1.2, 2.1, 2.2, 2.3, 2.4, 3.1 and 3.2 will be assessed by individual project work whilst the examination will assess LO1.1, 2.5 and 2.6. Oral feedback will be given during practical/laboratory sessions. Written feedback will be via assessments.
