Aims:
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.
To extend the ability to deal with normal force, shear force and bending moment in statically determinate beam assemblies with internal hinges and cranked members.
To introduce methods for determining the displacements in statically determinate beams, frames and trusses.
To introduce and develop understanding of the flexibility method, with applications to indeterminate beams, frames and trusses with a single redundancy.

Learning Teaching & Assessment Strategy:
Concepts are introduced using formal lectures. Deeper understanding is developed during tutorials, and further enhanced using the laboratory class. Oral feedback is given during the laboratory sessions and tutorials. 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.
