Learning outcomes:
O1 - Knowledge of the fundamental concepts of mechanics.
O2 - Knowledge of the concept of resultant forces and static equilibrium of a point.
O3 - knowledge of the concepts of reaction, forces and moments equivalent and static equilibrium of rigid bodies.
O4 - knowledge of the concepts of hypostatic, isostatic and hyperstatic mechanical systems.
O5 - Ability in the calculation and static analysis of simple and composite isostatic structures, with determination of support reactions and binding forces between sub-structures.
O6 - Ability in the calculation of internal forces in beams, articulated systems, portals and arcs, with the tracing of the respective diagrams.
O7 - Knowledge of the concept of elemental work of a force and a moment.
O8 - Ability in the application of the principle of virtual works to the calculation of support reactions and efforts in isostatic structures.
O9 - Knowledge in the basic mechanical and structural problems involving friction.
Syllabus:
C1 - Introduction to Mechanics: Fundamental concepts and principles, units, numerical precision.
C2 - Statics of material points: Equivalent systems of forces, resultant force, force polygon, equilibrium of a material point (2D and 3D).
C3 - Statics of rigid bodies: Forces and reactions, equivalent forces, moment of a force, resultant moment, equilibrium of rigid bodies.
C4 - Analysis and classification of mechanical systems: Hipostatic, isostatic a hyperstatic.
C5 - Diagrams of internal forces: Bending moment, shear force and axial force in beams, frames, arches and hinged structures.
C6 - Method of virtual work: Elementary work of a force and a couple. Principle of virtual work applied to hipostatic and isostatic mechanical systems.
C7 - Friction: Laws of dry friction. Friction coefficient, wedges.
Teaching Methodologies and Assessment Criteria:
This curricular unit has the duration of one semester, involving 60 hours of contact with the teaching team, 98 hours of autonomous work and 10 hours for evaluation (total: 168 hours). The course is credited with 6 ECTS. The classes are organized in theoretical –T (exposition of the subjects in a theoretical perspective, exemplifying the concepts through practical problems) and in practical classes – PL (solution of practical problems that cover all syllabus).
The evaluation is performed in to phases:
- Continuous evaluation: Evaluation through the individual solutions of problems related with all syllabus. This evaluation determines the possibility of submission to the final exam.
- Final exam (with theoretical and practical part) for admitted students.
