Aims
The aim of this module is to introduce students to the essential mechanical principles associated with engineering applications. Topics included in this module 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 module students will be able to explain the underlying principles, requirements and limitations of mechanical systems
Learning Outcomes
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.
