Engineering is a discipline that uses scientific theory to design, develop or maintain structures, machines, systems, and processes. Engineers are therefore required to have a broad knowledge of the science that is applicable to the industry around them.
This unit introduces students to the fundamental laws and applications of the physical sciences within engineering and how to apply this knowledge to find solutions to a variety of engineering problems.
Among the topics included in this unit are: international system of units, interpreting data, static and dynamic forces, fluid mechanics and thermodynamics, material properties and failure, and A.C./D.C. circuit theories.
On successful completion of this unit students will be able to interpret and present qualitative and quantitative data using computer software, calculate unknown parameters within mechanical systems, explain a variety of material properties and use electromagnetic theory in an applied context.
By the end of this unit students will be able to:
- Examine scientific data using both quantitative and qualitative methods.
- Determine parameters within mechanical engineering systems.
- Explore the characteristics and properties of engineering materials.
- Analyse applications of A.C./D.C. circuit theorems, electromagnetic principles and properties.
