The aim of this subject is to provide an introduction to modelling the stresses and deformations that occur when axial, torsional and flexural loads are applied to a body in static equilibrium, as well as the translational and rotational motions that eventuate in a body subject to different load applications. This material will be complemented with laboratory and project based approaches to learning.

The subject provides the basis for all the mechanical engineering subjects that follow. The calculations introduced in this subject are the most common type of calculations performed by professional mechanical engineers in all sectors of the industry.


Topics to be covered include free-body diagrams; equilibrium; force systems; stresses and strains; coordinate systems; statically indeterminate systems; flexure; bending under combine loads; torsion; power transmission; kinematics; relative motion; particle kinetics; impulse and momentum; vibration; rigid body motion; angular impulse and momentum; work and energy.

Intended learning outcomes

Intended Learning Outcomes (ILOs)

Having completed this unit the student should be able to:

1 - formulate problems in statics and dynamics by choosing suitable system boundaries and identifying relevant forces and coordinate systems;
2 - analyse the equilibrium of systems of forces in two dimensions;
3 - determine the loads and stresses experienced by components of common engineering structures such as trusses, frames and beams;
4 - describe and analyse the motion of particles and rigid bodies using three-dimensional vectors;
5 - apply the principles of impulse-momentum and work-energy to solve problems in the dynamics of simple machines and vibrating structures.

Generic skills

On completion of the subject students are expected to have the ability to:

  • apply knowledge of basic science and engineering fundamentals;
  • communicate effectively;
  • have in-depth technical competence in at least one engineering discipline;
  • undertake problem identification, formulation and solution;
  • function effectively as an individual and in multi-disciplinary and multi-cultural teams, with the capacity to be leader or manager as well as an effective team member.
