Unit Description and General Aims
The objective in presenting this unit is to provide students with an indepth study of the fundamentals of mechanics of materials and structures.
The subject matter covered in this unit will include: all relevant physical properties and fundamental laws governing the behaviour of materials and structures; the concepts of equilibrium and application of these to various structures; free body diagrams; forces, moments, and centres of mass; the forces of friction and rigid body dynamics; stressstrain analysis; shear force and bending moment diagrams; and, the effects of torsion.
Successful completion of this unit will serve as a key prerequisite for subjects involving mechanics of machines, and design of mechanical systems.
