Mechanical principles have been crucial for engineers to convert the energy produced by burning oil and gas into systems to propel, steer and stop our automobiles, aircraft and ships, amongst thousands of other applications. The knowledge and application of these mechanical principles is still the essential underpinning science of all machines in use today or being developed into the latest technology.

The aim of this unit is to introduce students to the essential mechanical principles associated with engineering applications.

Topics included in this unit are: behavioural characteristics of static, dynamic and oscillating engineering systems including shear forces, bending moments, torsion, linear and angular acceleration, conservation of energy and vibrating systems; and the movement and transfer of energy by considering parameters of mechanical power transmission systems.

On successful completion of this unit students will be able to explain the underlying principles, requirements and limitations of mechanical systems


Learning Outcomes

By the end of this unit students will be able to:

  1. Identify solutions to problems within static mechanical systems.
  2. Illustrate the effects that constraints have on the performance of a dynamic mechanical system.
  3. Investigate elements of simple mechanical power transmission systems.
  4. Analyse natural and damped vibrations within translational and rotational mass-spring systems.
