MECHANICAL ENGINEERING
Academic Year 2025/2026 - 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.
This course, in line with the United Nations 2030 Agenda for Sustainable Development, supports quality education (Goal 4), promotes decent work and economic growth (Goal 8), and fosters innovation and sustainable infrastructure (Goal 9).
Course Structure
Lectures and numerical exercises: 60 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
- 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 due tests.
Learning assessment may also be carried out on line, should the conditions require it.
Examples of frequently asked questions and / or exercises
