Methodologies
Methodologies   ::  
  Description
Problem solving, classroom exercises The teacher will guide students in the application of theoretical concepts and results to problem solving, encouraging critical reasoning at all times.
Laboratory practicals A practice will be carried out in the laboratory where the validity or otherwise of Navier Bernoulli's hypothesis for obtaining normal tensions is demonstrated.
Assignments Exercises will be proposed that students will solve outside the ordinary classroom, thus acquiring skill in using the tools necessary to solve problems.
Personal tuition The teacher will resolve the doubts raised by the student individually.
Lecture The teacher will introduce, through theoretical explanations and illustrative examples, the concepts, results and methods of the subject.

Personalized attention
 
Personal tuition
Description
The student who wants a tutorial will request it in advance.

Assessment
  Description Qualification
Mixed tests There will be three types of written tests:
1.- Final exam of the entire subject.
2.- Partial exam.
3.- Periodic individual work to be carried out by the student. 		1.- 70%
2.- 20%
3.- 10%
 
Other comments and second call

To pass the subject you will have to obtain at least a grade of 3.5 points out of 10 in test 1 in both calls. The subject is passed if the final grade is equal to or greater than 5 points.

In the second call, the results of tests 2 and 3 obtained throughout the semester are valid, although it is not mandatory to have taken them. In the second call, the exam will consist of two parts: a first corresponding to the midterm (20%) and another to the rest of the subject (70%). In the case of not having taken test 3 during the course, the part corresponding to the rest of the subject will have a weight of 80%.
