Educational Goals

Upon successful completion of the course the student should
• be able to identify and describe the various drive systems and their uses
• be able to select and calculate the necessary technical quantities of the drive systems, in order to analyze and synthesize mechanical structures.

General Skills

• Search, analysis and synthesis of data and information, using the necessary technologies
• Decision making
• Autonomous work
• Exercise criticism and self-criticism
• Promoting free, creative and inductive thinking

Teaching Methods

Face to face and/or distance lectures
Learning process support through the online learning platform of the course, which includes:
a) slides of the lectures,
b) recitations and detailed solutions of the main exercises for each sub-unit,
c) teaching notes adapted to the physiognomy of the offered study program,
d) communication with students via e-mail.

Students Evaluation

Students will be assessed with a written final exam that will include problem solving with a combination of knowledge of theory, calculations and critical evaluation (100%).
