Description


The subject Mechanisms and Machines II, centered in the description, interpretation and calculation of accionamientos and his auxiliary elements, completes the integral training in the field of the mechanisms and the machines. 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 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.
