Teaching Methodologies and Assessment Criteria	The classes in this course are theoretical-practical. The theoretical foundations are initially presented and then the practical applications, with calculation examples. Presentations are made using a computer and video projector. The practical component calculations are carried out on the table. All documentation is provided to students on an e-learning platform. Periodic evaluation is based on written tests.
Language	Portuguese. Tutorial support is available in English.
