Introduction. Gravity acceleration. Mass and weight. Notion of moment of a force. S.I. Units
Particle equilibrium. Notion of force. Traction and compression. Diagram of axial forces. Notion of tension and extension. Law of Hooke. Linear and non-linear behavior. Elastic and plastic behavior. Behavior fragile and ductile.
Cables and arcs. Stability. Efforts. Analogy between cables and arcs. Stability of domes and vaults.
Isostatic and hyperstatic structures: Degrees of freedom and connections to the outside. Balance conditions in space and plane. Types of support and reactions generated.
Isostatic trusses. Method of the nodes and method of the sections. Identification of the type of stress to which each bar is subject: traction or compression.
Efforts in linear rigid bodies: Transverse stress, Bending and torsor moments. Determination of the reactions in the supports. Sign Convention. Diagrams of stresses (transverse stress and bending moment).

Teaching Methods

The course is organised into theoretical-practical classes, which are organised into oral presentations, exercises and discussions.

Assessment

Grading in this course unit can be based on one of the following assessment schemes: continuous assessment or final exam.
Continuous assessment by frequency test: Final grade = (0.80xF) + (0.10xAM) + (0.10xA)
Assessment by regular examination: Final grade = (0.80xEN) + (0.10xAM) + (0.10xA)
Assessment by exam in appeal period, special period exam and extraordinary period exam: Final grade = (1.0xE)

Where:
Final grade - cannot be less than 10 points.
F - 2 frequency tests with an arithmetic average of no less than 10 marks and a minimum mark of no less than 7.5 marks for each assignment.
EN - exam with a minimum mark of 10.
E - exam with a minimum mark of 10.
AM - keeping up with the subject throughout the semester.
A - attendance.

Class attendance is compulsory (75% of classes).
