Labs / Practicals
The practical aspects will be addressed in Materials Labs Analysis and Simulation lab ‘Simulation lab’ on Thursday morning covers: Mechanics labs in Semester 1 Dynamics labs in Semester 2 Emphasis here is primarily on using computer simulation tools i.e.
Finite Element Analysis and Mechanism/Motion simulation. This is independent of Engineering Des, Analysis and Sim with C Doran.

Final Year Project The Final Year Project is the most important part of the
course as it demonstrates your ability to apply the knowledge and skills gained over the duration of your studies; to work independently and in a methodical manner, in the delivery of a substantial technical project.
Important stages in this activity will include:
- Project selection - Interim presentation - Planning structure of thesis (title / chapter headings) - Submit unbound to ensure layout/formatting are OK - Have thesis proof read to catch errors. - Submission of final bound thesis - Engineering Expo - Final presentation
![Page 12: No Slide Title › staff › sdalton › ME4 › ME4... · Final Year Project Continued… Year long / Individual project /10 credits Desirable for a project to have a practical aspect](https://reader033.vdocuments.mx/reader033/viewer/2022060209/5f0465f77e708231d40dc6a4/html5/thumbnails/12.jpg)
Final Year Project Continued… Year long / Individual project /10 credits Desirable for a project to have a practical aspect e.g.
physical testing or measurement. Projects may come from one of the following:
- List of projects presented by staff. - Ideas drawn from your own experience/interests. - Industrially based project.
It is essential that all projects contain a strong analytical / technical content.
It is essential that the engineering analysis carried out contains a level of mathematical treatment appropriate to a Bachelor of Engineering Honours degree in Mechanical Engineering.

Mechanics-Finite Element Analysis Finite element analysis enables the designer to
analyse the stresses in a component. When a force is applied to a component stresses are induced. Finite element analysis enables the stresses to be determined. Blue represent low stress and Red represents high stress.

Use of computer simulation
Computer simulation should never be taken at face value.
All analysis must be supported by manual calculation, or experimental work or both.
