Manutenção Mecânica

Approval in curricular units that integrate the “General and Scientific” and “Technical” training components of the course.

In theoretical classes a theoretical exhibition of each subject is made.
In theoretical-practice classes the theoretical exposure is supplemented and good maintenance practices are analyzed. Procedures and equipment used in asset maintenance are also studied.
In practice-lab classes, practice diagnostic, maintenance and repair cases are resolved.

Lubrication: Factors influencing lubricant selection; Examples of calculations for lubricant selection; Practical testing of new and used lubricants.

1.1-The first component, when carried out through continuous and periodic assessment, comprises two written tests, scheduled up to the 3rd week of classes. Access to these tests requires a minimum attendance of 75% of all theoretical, theoretical-practical, and practical-laboratory classes already completed on the date of each test (A1).
1.2-A second continuous assessment component corresponds to the evaluation of performance in the practical-laboratory classes, with the preparation of two written papers/reports and corresponding oral presentations and discussions, in groups of two students, exceptionally one (B). All papers must be submitted to faculty and discussed by December 14, 2025.
2-Both the final exams and the final exams will last a maximum of two hours and will be worth 20 points. 3. If the student does not meet the passing requirements established for written assignments/reports on laboratory activities, they will fail and may only be re-evaluated in subsequent academic years. The assessment schedule will indicate NRC (Does not meet the requirements).
4. Student approval is conditional upon meeting the following requirements:
a) Attendance at least 75% of classes;
b) Obtaining a minimum of 9.5 points in the average of the grades of the two tests or the final exam and in the presentation and discussion of the written assignments/reports;
c) Having achieved a minimum of 8 points in one of the tests, since it is compensated with a minimum grade of 11 points in the other test. If the grade in one of the tests is less than 8 points, the student will be required to take a final exam covering the entire course material;
d) Having achieved a minimum of 8 points in one of the written assignments/reports on the practical-laboratory component, provided it is compensated with a minimum grade of 11 points in the other test.
e) The preparation and presentation of the two written assignments/reports is weighted 30%, and the oral discussion is weighted 70% in determining the grade for both written assignments/reports.
f) Obtaining an average grade of at least 9.5 points, on a scale of 0-20 points, in the practical-laboratory component mentioned in 1.2.
g) Obtaining at least 9.5 points in the "Final Grade," calculated using the following formula:
Final Grade = (0.75*(A1 or A2)+0.25*B)
Grade in assessment component 1.1 (A1); Grade in the final exam (A2); Grade in assessment component 1.2 (B).

OTHER CONDITIONS:
In the theoretical-practical and practical components, students may only use scientific calculators.
In any of the continuous assessment components, each student may only prepare and defend reports on experimental work in which they have participated. The written work/report completed in the current academic year will not be accepted or valued in subsequent academic years.
