Aims:
(1) To evaluate the concepts of a general three-dimensional stress and strain state and to relate these concepts to the behaviour of actual materials and structural elements.
(2) To establish knowledge of the concepts, design, analysis and application of machine dynamics.
(3) To be able to use Adams to analyse and design dynamics of mechanical systems.

Learning Teaching & Assessment Strategy:
Concepts are introduced using formal lectures. Deeper understanding is developed during problem-solving classes, and further enhanced using the laboratory class. Oral feedback is given during the laboratory sessions and problem-solving classes. Written assessment will concern the application of practical skills to the knowledge base of the module and the formal examination will assess the wider learning outcomes expressed in the descriptor.
