Programme

The course provides methods for designing mechanical structures and selecting machine components.
The course program covers the following topics:
- Mechanical design in the presence of static loads (Cauchy stress tensor, safety coefficients, Möhr circle, Yield criteria for metals, stress concentration factors)
- Fatigue design
- Mechanical testing of materials (Tensile Testing, Hardness Testing, Creep Testing, Impact Testing, Non-Destructive Testing, Fractography)
- Plain, ball and roller bearings
- Hydrodynamic Bearings
- Mechanical shaft-hub connection
- Fastening and Joint Design (welding, nailing and adhesive bonding)
- Spring sizing and selection

Type of evaluation

Verification of learning is through a written test (2 hours) and an oral examination (about 30 minutes). The written test is organized through a number of exercises on the sizing of mechanical shafts and the selection of mechanical components and is aimed at testing the level of effective understanding of the concepts and the students' ability to apply them in simple real-world contexts. The oral examination focuses on the theoretical topics covered in various parts of the course, as well as the correct representation of simple mechanical components. In evaluating the examination, the determination of the final grade will take into account the level and quality of knowledge of the topics, the ability to expound on them clearly, as well as the use of vocabulary appropriate to the specific technical engineering context.
