Specific skills
  • E9_Know the basics of science, technology and chemistry of materials. Understand the relationship between microstructure, synthesis or processing and material properties

     

  • E13_Know and use the theory of machines and mechanisms

     

  • E14_Know and use the principles of material resistance

     

Description


The subject of Mechanical Systems refers to the statics and dynamics of rigid bodies where the fundamental principles of general mechanics applied to the behavior of solids are explained, both in a situation of static equilibrium and in dynamic movement of translation and rotation. These principles are related to Newton's laws applied to forces and moments.

Fields of application within engineering are related to the design of structures, machines and mechanisms.

This subject has methodological and digital resources to make possible its continuity in non-contact mode in the case of being necessary for reasons related to the Covid-19. In this way, the achievement of the same knowledge and skills that are specified in this teaching plan will be ensured.
The Tecnocampus will make available to teachers and students the digital tools needed to carry out the course, as well as guides and recommendations that facilitate adaptation to the non-contact mode.

Learning outcomes


At a general level, this subject contributes to the following learning outcomes specified for the subject to which it belongs (Mechanical and Materials Engineering)

  • Analyze and size structures. (CE9)
  • Knows, understands and uses the principles of machines and mechanisms. (CE13)
  • Write texts with the appropriate structure for communication objectives. Introduce the text to an audience with the right strategies and means. (CE13)
  • Know and put into practice the way and dynamics of teamwork (CE8, CE9, CE13, CE14)
  • Identifies one's own information needs and uses the collections, spaces and services available to design and execute searches appropriate to the thematic area (CE8, CE9, CE13, CE14)
  • Carry out the tasks assigned based on the basic guidelines given by the teacher, deciding the time to be used in each section, including personal contributions and expanding the sources of information indicated. (CE7, CE8, CE9, CE13, CE14)

Working methodology


  • Expository class sessions based on the teacher's explanation.
  • Laboratory practice sessions with individual work with computer or with small group work.
  • Non-contact activities dedicated to the resolution of practical exercises based on the data provided by the teacher.

In the theoretical sessions the students have all the necessary information to follow the explanations of the professor and / or to study them of autonomous form by means of the notes, so much of theory as of multitude of problems solved and others that have to solve the students. 

The organization of the subject consists of differentiating the class activities and the activities of the students, these are in the eCampus of the subject defined and classified in the timetable.

In the practical laboratory sessions, the practical part of the theoretical concepts is deepened, taking measures of various types, carrying out theoretical calculations and their experimental verification, at the same time as conclusions are drawn from them.

Learning activities


A series of activities of an eminently practical nature (short exercises, problems ...) are made available to students, which are the basis of the learning activities of the subject. These activities will have to be solved by the students, often in a non-contact way, following the instructions of the teachers and will also be worked on in class.  

In order to gather evidence of the achievement of the expected learning outcomes, the following evaluative activities will be carried out:

Face-to-face activities:
- Exhibition of contents. (Evidence of CE13 learning outcomes)
- Carrying out laboratory practices in teams of few students (Evidence of learning outcomes CE13, CB5)
- Resolution of exercises, problems and cases, possibly with computer support, with the participation of the student. (Evidence of the learning results CE13, CB4, CB5)

Non-Face-to-Face Activities:
- Completion of exercises or theoretical or practical projects outside the classroom, individually or in groups (Evidence of learning outcomes CE13, CB4, CB5)
- Study, work and personal analysis. (Evidence of learning outcomes CE13, CB5)
- Tutoring and formative evaluation of the learning process (Evidence of learning outcomes CE13, CB5)

The activities are divided into theoretical and practical sessions. In the theoretical sessions the students have all the necessary information to follow the explanations of the professor and / or to study them of autonomous form by means of the notes, so much of theory as of multitude of problems solved. The activities are programmed by the students in the eCampus differentiating the activities inside the classroom (class activities) from the activities of the students outside the classroom (student activities). The activities proposed to the students correspond to the resolution of problems and to the study of concrete subjects proposed to deepen in concepts explained in class. In the practical sessions the activities promote the development of skills for experimentation, such as identifying and using laboratory material, control of variables and relevant data, hypothesis and teamwork.

Evaluation system


There will be two exams during the course, a first partial and a second partial or final exam. Apart from laboratory practices.

The final grade is the weighted sum of the exams, laboratory practices and assignments, with the following percentage:

FINAL GRADE = (EXAM 1)x(0,4)+(EXAM 2)x(0,4) + (PRACTICES + ASSIGNMENTS)x(0,20)

o

FINAL GRADE = (FINAL EXAM)x(0,8) (PRACTICES + ASSIGNMENTS)x(0,20)

To be able to access the weighted sum, the exams must be passed with a minimum grade of Pass 4.

There will be an extraordinary recovery session for the exam for all students who do not pass the subject in the ordinary assessment.

The grade of this recovery will replace the exam grade obtained in the ordinary evaluation.
