Learning outcomes |
This course aims to provide students with knowledge in the design of machines, mechanisms, and mechanical components. By the end of this course, students should be able to:
-Understand the fundamental concepts of the theory, principles of operation, and applications of a set of mechanical components,focusing on power transmission in mechanical systems through flexible elements and gears.
- Develop skills in the dimensioning calculation of components, such as chains, belts, gears, brakes, clutches, and flywheels.
-Apply the theoretical concepts acquired, complementing the knowledge gained in the undergraduate course on Mechanical Components, to solve real problems in the context of mechanical component design.
-Acquire the ability to select, develop, and integrally design the mechanical components that make up mechanisms or machines, based on the functional requirements of a mechanical system.

Teaching Methodologies and Assessment Criteria |
Students will be evaluated through two continuous assessment tests, (F1) and (F2), which aim at the practical application of theory to the calculation of component sizing, using the theory taught in the classroom and applied to mechanical systems that integrate the various components addressed. The final average of the Teaching/Learning assessment is calculated using the formula:
FINAL AVERAGE = (F1 +F2)/2.
The approval criteria for the Teaching/Learning assessment is defined as FINAL AVERAGE (FA) >= 9.5.
Students with a FINAL AVERAGE (FA) >= 6 are eligible for the exam.
The approval criteria for the Exam assessment is defined as EXAM >= 9.5.
