###
**1.1. Introduction**

Short presentation of the course

Strength of Materials (also known as Mechanics of Materials) is the study of the internal effects of external forces applied to structural members. Stress, strain, deformation deflectio, torsion, flexure, shear diagram and moment diagram are some of the tpics covered by this subject.

The knoledge of this subject is a must in all engineering studies.

###
**2.1. Learning goals**

The student, in order to pass the course, will have to demonstrate the following results:

1. The student is able to understand the concepts of stress and strain and its relationships

2. The student knows how to calculate shear and moment diagrams

3. The student is able to solve torsion and bending problems

4. The student is aware of the buckling phenomenon

5. The student is able to aplly the knowledge of strength of materials on engineering applications and design problems using a computer program

###
**5.1. Methodological overview**

Teaching methodology

Teaching for this course will consist primarily of lectures where the fundamental theory will be presented, followed by examples to illustrate how the theory can be applied to solve practical engineering mechanics problems. Students will learn how to use computer programs to apply the knowledge of strength of materials, that has been described in the lectures, on engineering applications and design problems. They will be required to perform calculations using the results of the programs to demonstrate their understanding of the underlying theory. Students will develop their understanding of the course content through the reading of the textbook, practice problem solving through tutorial questions and attendance at lectures where problem solving strategies are presented and discussed.

###
**5.2. Learning tasks**

The distribution of the learning activities during the semester of the course is:

- Lectures (1.8 ECTS): 45 hours.

- Laboratory sessions (0.48 ECTS): 12 hours.

- Guided assignments (0.6 ECTS): 15 hours.

- Autonomous work (2.92 ECTS): 73 hours.

- Evaluation (0.2 ECTS): 5 hours.

- Tutorials

Lectures: the professor will explain the theoretical contents of the course and solve illustrative applied problems. These problems and exercises can be found in the problem set provided at the beginning of the semester. Lectures run for 3 weekly hours. Although it is not a mandatory activity, regular attendance is highly recommended.

Laboratory sessions (Experimental lab and computing lab): sessions will take place every 2 weeks (6 sessions in total) and last 2 hours each. Students will work together in groups actively doing tasks such as practical demonstrations, measurements, calculations or simulations.

Guided assignments: students will complete assignments, problems and exercises related to concepts seen in laboratory sessions and lectures. They will be submitted at the beginning of every laboratory sessions to be discussed and analyzed. If assignments are submitted later, students will not be able to take the assessment test.

Autonomous work: students are expected to spend about 73 hours to study theory, solve problems, and prepare lab sessions.

Tutorials: the professor's office hours will be posted on Moodle and the degree website to assist students with questions and doubts. It is beneficial for the student to come with clear and specific questions.
