| General description | This subject studies the fundamentals of analysis and synthesis of mechanisms, as well as the tools for their simulation, including kinematics, dynamics and graphic representation. For this purpose, some specific mechanisms will be explained and analyzed, such as bearings, gears and inertia wheels. Theoretical exercises will be carried out, as well as practical analysis by means of computers. | |||||||||||||||||||||

| Methodologies |
| Description | |
| Problem solving, classroom exercises | In these sessions the teacher will guide students in the application of concepts and and theoretical results to the solution of problems and its modelling in mechanical engineering, fostering in every moment attitudes of reasoning and discussion. Some extra excercises will be proposed to the students to be solved by them so that they acquire skills in the use of the tools for problems resolution. |
| Practicals using information and communication technologies (ICTs) in computer rooms | In the computer room the student will be trained in the use of CATIA program, which is a very useful tool for the analysis and synthesis of mechanisms, as well as simulation. |
| Assignments | The students will be asked to perform a practical work in which they will analyse specific mechanisms, taking into account all the variables involved in their operation. |
| Personal tuition | Tuition sessions will be held for consultation and resolution of doubts or to make clearer some theoretical or practical aspects of the subject. In these sessions the individual view of the student will be complemented with that of other students so that a better understanding of the subject can be achieved. |
| Lecture | Lectures will be used by the teacher to introduce the concepts of the subject by means of theoretical explanations and illustrative examples. The student will devote at least a 5% of her/his work without teacher to prepare these classes reading what the teacher previously had pointed out. |

| Assessment |
| Description | Qualification | ||
| Lecture | There will be a partial exam at the middle of the semester in which the students will have to answer theory questions and solve some problems | 10% | |
| Practicals using information and communication technologies (ICTs) in computer rooms | The skills acquired by using the computer tools will be assesed through the results obtained by each student at the end of the classes. | 30% | |
| Assignments | Every group will hand a summary of the work to the teacher, who will review it to assess its coherency and the understanding of the concepts by the students. | 30% | |
| Objective short-answer tests | The test will consist in questions about specific aspects of the theoretic contents of the subject. These questions must be answered in a few written lines to prove the understanding of those contents. | 10% | |
| Practical tests | These tests will consist in the individual resolution of numeric problems in which the understanding of the theoretic contents will be shown as well as the ability to apply them to specific cases. | 20% | |
| Other comments and second call | |||
| <p>A minimum mark of 5 in the Objective short-answer tests and in the Practical tests will be necessary as well as an average mark of 5 to pass this subject.</p><p>In case of failing the subject in the first call the student must take other Objetcive short-answer test and Practical test in the second call. If the student had already passed the Assignments and the Practicals in the computer room it will not be necessary to be assessed again about them. If the student didn't pass these two parts, she/he will take an exam on the corresponding contents. In the second call the same criteria as in the first one regarding minimum marks will be applied.</p> | |||
