Skills


Basic skills
  • B2-That the students know how to apply their knowledge to their job or vocation in a professional way and have the skills that are demonstrated through the elaboration and defense of arguments and the resolution of problems within their area of 'study

  • B4_That students can convey information, ideas, problems and solutions to both specialized and non-specialized audiences

     

Specific skills
  • Have knowledge and skills for the calculation, design and testing of machines

Description


The subject deals with fundamental issues regarding the conditions and regulations of machine design. It is a key element for the consolidation of learning, as it allows students to apply in the design of machine elements that has been worked on in other subjects. On the other hand, it is a key source of theoretical and applied knowledge for the professional practice of the mechanical engineer with regard to the conditions and regulations of machine design.

Evaluation system


The calculation for the Final Grade of the subject is:

NF = 0,3 Ex1 + 0,3 Ex2 + 0,2 Vid + ​​0,2 Pr

  • NF: Final Note
  • Ex1: 1st Partial Exam.
  • Ex1: 2nd Partial Exam.
  • Vid: Integrator Video Note.
  • Pr: Average grade of practices.

Clarifications:

  • Minimum grade for each exam is 4 (four). In the event that any of the grades for Ex1 and Ex2 activities are below the minimum grade, the final grade for the subject will be limited to 4.
  • The minimum Pr grade is 4. If the Pr grade is below the minimum grade, the final grade of the subject will be limited to 4.
  • The minimum Vid grade is 4. If the Vid grade is below the minimum grade, the final grade of the subject will be limited to 4.

Recovery:

  • In the recovery period only Ex1 and Ex2 are reassessed. The rest of the activities are not recoverable.
  • The minimum marks established for all activities are maintained.
  • The previous calculations will be applied to obtain the final grade of the subject.
