Fundamentals of mechanics

In the theoretical-practica lclasses the expository and inquisitorial methods are used. During the approach to programmatic issues, students are encouraged for a critical attitude and the physical understanding of them, with an active participation in the class? student proceed to solving exercises individually or in groups.
In tutorial classes, individual learning skills and teamwork are explored by answering questions and monitoring of the proposed work.
Evaluation: is carried out on an individual written Final exam, about the subjects taught.
The Final exam is evaluated in the range to 20 points, and the approval requires a mark greater than or equal to 10 points. It is planned to carry out written or oral examination to students who require special exams.

Goals:
Toknow and understand the constitution of a structure (elements, supports and internal joints) and the actions that may occur on it? to know the mechanisms of transfer of actions/loads on structures? to know and apply the static equilibrium equations to determine the support reactions of trussstructures and the distribution of internal forces? to calculate geometric properties of sections?
To know and to understand the properties of the fluids? to know and to master the concepts related to the hydrostatic? to understand the concepts of hidrocinematics, to know and to apply the fundamental principles of fluid dynamics?
Skills:
Generic
– Seizure capacity and application of knowledge, conduction of judgment and decision making? communication and selflearning.
Specific
– The course provides the basis of Newtonian Mechanics and hydrostatic for students to understand the fundamental
