Mechanical Principles

Module summary

Module code: MECH1082
Level: 4
Credits: 15
School: Engineering and Science
Department: Engineering
Module Coordinator(s): Alexis Kordolemis



To provide students with the fundamental principles and concepts involved with mechanical engineering. This Module is designed to give students an introduction to fluid, dynamics, mechanics and thermodynamics and their applications in engineering systems. The emphasis is on Newton’s laws as applied to static and dynamic systems along with a descriptive approach to fluid mechanics and thermodynamics in real world applications. This approach will enable students to build upon these principles in their future studies.

Learning outcomes

On successful completion of this module a student will be able to:
1 Apply Newton’s law to both static and dynamic systems.
2 Analyse fluid in motion and calculate quantities associated with Bernoulli’s equation.
3 Describe thermodynamic cycles, laws of thermodynamics and conservation of energy.
4 Report on the procedure and outcome of experimental work and formulate appropriate conclusions.
