Learning outcome

Knowledge:
The course gives knowledge of:
- Machine elements and their design, functional principles, mechanisms, and integration in machinery.
- The functions of some common machine elements and the solution of design and engineering problems associated with these.
- How to establish structural and dynamics models for mechanical behavior with basis in subsystem or component.
- The application of design criteria for different (mechanical) functional and design requirements for various machine elements and components.
- Choice of reasonable design and engineering solutions with basis in basic understanding of mechanical behavior and design criteria.

Technical skills:
The student shall master the following:
- Apply knowledge from basic courses such as mathematics, physics, mechanics, statics, (strength of) materials to evaluate, design and engineer real components/machine elements.
- Simplify basic machine systems into representative models for mechanical analysis.
- Perform simple predictions, providing a basis for more effective and right evaluation of critical factors and issues associated with (design) robustness of machine components.
- Provide the necessary competence to carefully evaluate results obtained by more advanced numerical analysis methods such as FEM.

General competence:
The student shall on general basis have knowledge of:
- Main steps and considerations included in an engineering process for machine elements.
- Understand on general basis reasonable, sound design principles for selected machine components.
- General design and engineering principles for machine elements subjected to static and dynamic loads.
- On an independent basis capture knowledge of more complex machine elements and design and engineering principles.
