1. General information
The main objective of this subject is for the student to acquire the ability to analyze mechanical systems from the kinematic and dynamic points of view, and if necessary, from the static point of view. As tools for this analysis, the motion composition, the free solid diagram, the equations of motion, the equations of equilibrium... will be used.
In addition, the student will be able to develop simulations of the behavior of mechanical systems using computer programs.
These approaches and objectives are aligned with the Sustainable Development Goals (SDGs) of the 2030 agenda of United Nations (https://www.un.org/sustainabledevelopment/es) and certain specific targets, such that the learning outcomes of the subject contribute to some extent to the achievement of target 9.4 of goal 9.
2. Learning results
- To analyze kinematically a mechanical system, both planar and 3D, calculating velocities and accelerations of any of its points.
- Apply the concepts of motion composition to the analysis of complex motions.
- To know the concept of instantaneous center of rotation and its application in plane systems for the determination of velocities.
- Define and identify the motion parameters of a mechanical system and its degrees of freedom.
- Perform the dynamic and, if necessary, static analysis of a mechanical system, using as main tool the free solid diagram. Identify and calculate the forces generated in the interaction between the components of a mechanical system.
- To determine and apply the concepts of center of mass and inertia tensor to the elements of a mechanical system.
- Apply the vector theorems and the energy theorem to mechanical systems and interpret the results obtained.
- To understand the phenomenon of friction, both in static and dynamic situations.
- Develop simulations of the behavior of mechanical systems using computer programs.

4. Academic activities
- Lectures (type 1): 30 hours
The basic theoretical knowledge of the subject is presented with its direct application in problem solving.
- Types of problems (type 2): 15 hours
Practical exercises of varying difficulty are solved in class.
- Computer practices (type 3): 15 hours
Using computer programs, various mechanical systems are analyzed from the kinematic, static and dynamic points of view.
- Teaching assignments (type 6): 20 hours
- Personal study (type 7): 67 hours
- Assessment test (Type 8). 3 hours
5. Assessment system
Option 1: Continuous assessment
- Exam (70% of the final grade). On the date of the official exam of the first call, there will be an exam that will evaluate the complete content of the subject. Minimum grade required in this exam: 5 points out of 10.
- Practices (15% of the final grade). 5 sessions of 3 hours each. Each session will have a script and a sheet of results that will be delivered at the end of the session with the results obtained.
- Statics partial test (15% of the final grade). Once the explanation of topic 4 has been completed, a partial test will be given. It will consist of solving several problems in which free solid diagrams of systems mechanical in static equilibriumwill have to be made.
In addition to these activities, during the course we will propose the realization of a work divided in 2 stages. It will consist of the manual calculation of the kinematics and dynamics of a given mechanism. Dates will be set for the completion of each stage and the detailed resolution will be published in the ADD so that each student can self-correct.
Option 2: Global assessment
- Exam (85% of the final grade). Minimum grade required in this exam: 5 points out of 10.
- Practical exam ( 15% of the final grade). It is not necessary to take a practice exam if the practices have been completed during the term.
In the 2nd call, only the global assessment option is possible.
