1. General information
The objective is to train the student to be able to design machine elements through the failure criteria, and to select the optimal materials for the design of an element.
These approaches and objectives are aligned with the following Sustainable Development Goals (SDGs) of the United Nations 2030 Agenda, so that the acquisition of the subject learning results provides training and competence to contribute to some extent to their achievement:
- Objective 8.2. Achieve higher levels of economic productivity through diversification, technological upgrading and innovation, including by focusing on high value-added and labor-intensivesectors.
- Objective 9.4. By 2030, upgrade infrastructure and convert industries to be sustainable, using resources more efficiently and promoting the adoption of clean and environmentally sound technologies andindustrial processes , with all countries taking action in accordance with their respective capabilities.
2. Learning results
The student, in order to pass this subject, must demonstrate the following results...
- Select the most suitable material or treatment for the application.
- Model or solve the drive mechanisms of subassemblies or mechanical machines, from drawings or specification notebooks.
- Dimension mechanical elements according to specifications.
- Design or analyze, using computer tools; the behavior of parts, subassemblies or systems, against established systems, against established stresses or performance requirements.
- To perform the kinematic and kinetic analysis of mechanical assemblies, machines and mechanisms analytically or by means of numerical simulation, analyzing the results obtained.
- Calculate and design structural elements subjected to loads.
- Drawing and interpretation of plans and diagrams according to the appropriate standards and symbology.
3. Syllabus
Contents
The theoretical contents are articulated on the basis of three didactic units, as shown in the table below.
Topic 1. Static Resistance Design
1.0. Review of straight beams and element design
1.1. Curved beams
1.2. Variable section beams
1.3- Contact stresses
1.4- Voltage concentrators
1.5. Theories of failure for static loading
Topic 2. Dynamic Strength Design
2.1. Dynamic loads
2.2. Impact load design
2.3. Fatigue strength design
Topic 3. Fasteners and transmission elements
3.1. Gears
3.2. Axles and shafts
3.3. Screws and bolts
4. Academic activities
The planned activities are:
- Theoretical classes: taught in a fundamentally expository manner by the teacher.
- Practical classes: the teacher solves problems or practical cases.
- Individual tutoring: through personalized attention, on an individual basis, with the teacher.
They may be face-to-face or virtual.
The distribution of the subject will be as follows:
- 54 hours of class with 20% of theoretical exposition and 80% of problem solving.
- 6 hours of written evaluation tests, at a rate of two hours per test.
- 90 hours of personal study, spread over the 15-week semester.
5. Assessment system
Two options:
1. CONTINUOUS ASSESSMENT
It is mandatory to attend at least 80% of the classes.
Qualifying activities:
• Exercises, theoretical questions and proposed works: The professor will propose exercises, problems, practical cases , theoretical questions, etc. to be solved individually. It represents a 10% of the final grade of the subject.
• Written tests: The tests will include theoretical and/or practical questions. There will be 3 tests spread over the semester . It represents 90% of the final grade of the subject. The final score will be the average arithmeticmean of the three tests, being the minimum grade for each of them 4 out of 10 to pass.
Prior to the first call, the teacher of the subject will notify each student whether or not they have passed the subject based on the use of the split evaluation system, based on the sum of the marks obtained in the different activities obtained in the different activities developed throughout the course, each of them contributing a minimum of 50%.
2. GLOBAL ASSESSMENT
Qualifying activities:
- Written exam: single test of resolution of exercises of theoretical and/or practical application. It is a 100 % to the final grade of the subject.
