MECHANICAL ENGINEERING
Academic Year 2022/2023 - Teacher: Rosario SINATRAExpected Learning Outcomes
The course aims to train engineering students in kinematic and dynamic modeling of the main mechanical systems and machines, the study of the vibrations of mechanical systems with one or more degrees of freedom, the study of robotic mechanical systems.
Computer numerical exercises will be carried out during the course.
Course Structure
Lectures for 25 hours;
Numerical exercises for 37 hours.
If the teaching will be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements.

Learning Assessment
Learning Assessment Procedures
- the presentation of an exercise that is assigned during the academic year. This paper presented by the end of the course allows access to the oral exam;
- a written test consisting in the study of a mechanical system with the methods studied during the course;
- an oral test based on knowledge of the contents, the relevance of the answers to the questions asked, the ownership of technical language, the ability to make connections between the contents of the program.
The final evaluation will be determined taking into account the evaluation of the three tests.
Learning assessment may also be carried out on line, should the conditions require it.
