– Ability to carry out research, reading and interpreting content analysis.
– Ability to summarize and write text
– Computer knowledge from the user’s perspective, digital writing of documents and creation of work and presentation and dissemination reports.
– Ability and motivation to research, use and apply specific software for the mechanics of structures and hydraulic systems.
– Sense of cooperation, mutual help, collaboration and a spirit of sharing knowledge, with practical interest in carrying out activities, individually and in work groups.
– Motivation, interest in acquiring elementary concepts of physics and mathematics, such as: Quantities and systems of units, Notion of vectors and their characteristics, Notions of force and principles of balance, Bases of trigonometry, the application of concepts to the study of mechanics.

Classes will be taught in Portuguese, with the objective of working and learning the syllabus presented. It is expected that classes will have, whenever possible, different moments in the knowledge transmission methodology:

1) monitoring the learning achieved by students, clarifying doubts and supporting practical guidance of work and/or solving exercises/problems;

2) expository presentation of content by the teacher, with eventual practical resolution of example exercises, followed by discussion between teacher, students and groups of students on the topics and exercises presented.

An expository presentation will be used during the explanation of theoretical subjects to support learning with practical exercise resolution. Students will be encouraged to carry out practical work on technical-scientific interpretation and on content and practical interpretation approaches through individual and group research.

As long as it is feasible, the possibility of visiting works or structures, whether on the Institute’s own campus or outside it, is considered during class hours. When this occurs, students will be challenged to present images and descriptions of the situations observed.

Goals:

1. Acquisition of fundamental concepts and tools within the scope of structural mechanics and fluid mechanics, serving as a basis for other curricular units.
2. Understand the constitution of a structure (elements, supports and internal connections) and the actions that can occur within it;
3. Know the mechanisms for transferring actions/loads in structures, and the effects of traction, compression, bending and shear.
4. Know and apply the static equilibrium equations to determine the reactions of the supports of lattice structures and the distribution of internal forces;
5. Know and understand the properties of fluids; know and master the concepts related to hydrostatics;
6. Understand the concepts of hydro-kinematics; know and apply the fundamental principles of
hydrodynamics.

Generic Skills:
– Increased skills in the areas of communication and transfer of knowledge;
– Application and demonstration of skills acquired through study and personal work methods in individual and group tasks;
– Motivation to use self-learning and skills development methods accompanied by the planned teaching methods;
– Application of knowledge and physical understanding of phenomena through technical, scientific and pedagogical interconnection;

Specific Skills:
– Acquire knowledge and ability to understand the mechanical behavior of building structures and structural elements
– Promotion of observation skills in practical situations aiming at the need for intervention;
– Encouraging the development of analysis and calculation methodologies in response to actions and effects in structures;

This subject provides the foundations of Newtonian Mechanics so that students understand the fundamentals of structural analysis and design of hydraulic systems and fluid mechanics. It contributes to their success in the Curricular Units of the curriculum and thus, in the acquisition of essential bases and decision-making capacity as future professionals.
