Teaching Methodologies
In theoretical lessons the content is presented through the use of both the board and PowerPoint slides. In theoreticalpractical
classes typical exercises are solved.
The evaluation of this curricular unit is performed through a written exam at the end of the semester. This exam consists of two parts, a theoretical component and a theoretical-practical one, corresponding to 30% and 70% of the final grade, respectively.
Learning Results
The main objective is to acquire the fundamental concepts and tools in the context of applied physics to Engineering, particularly in the field of statics. It is intended to introduce the preparatory basic content for other curricular units, namely, for Strength of Materials and Machine Elements. At the end of this curricular unit the learner is expected to be able to perform free-body diagrams of a rigid body subjected to several force systems. Apply the static equilibrium equations. Apply the method of sections in the design of structural planar trusses. Analyse friction in several machine elements. Calculate gravity centres of line segments, areas and
volumes. Determine moments of inertia, products of inertia, principal axis and principal inertia moments for areas.
