Overall objectives:

1 - Develop the ability to analyse problems in the mechanics of material point systems and rigid bodies at rest (static);
2 - Develop skills in the study of the principles of isostatic structures, determination of deformations and deformed structures isostatic;
3 - Deepening of general knowledge regarding the behaviour of hyperstatic structures

Assesssment methods and criteria:

Classification Type: Quantitativa (0-20)

Evaluation Methodology:
In accordance with the expected for the Professional Higher Technical Courses. The evaluation model adopted is model A. Normal Season: the evaluation will be carried out through two frequencies, each with a weight of 35% in the final classification, and two works with a weight of 15% each. These four elements of evaluation have a minimum score of 7.5 values and the works cannot be recovered on appeal. Season of Appeal and Special Season: the evaluation will be carried out through an exam, with a weight of 70% in the final classification, and of the two works carried out in the Normal Season of Evaluation, with a weight of 15% each. The three assessment elements mentioned have a minimum score of 7.5 points.
