Mechanical Technology

Not applicable.

In theoretical classes, a theoretical exposition of each subject is made.

In theoretical-practical classes, equipment and tools are identified and a demonstration of their use is made.

In practical classes, practical work is carried out to apply the knowledge transmitted in the theoretical and theoretical-practical component.
