In the theory lessons the subject is explained from basic principles. In the theory-practical lessons problems of real world interest are solved. In the Laboratory lessons there is experimental work where the students can solve practical problems and there is the submission of a report until the end of the lesson. The laboratory lessons imply 4 practical works from which the best of three are selected.
Each practical will be marked 1 to 4 and a total score of under 2 will prevent the student from getting a pass on the subject. In case it is equal or superior to 2 in a minimum of 3 practicals approval is calculated in the following way
Practical component (laboratory) – 20%, exam 80%
Final grade = 0.8*Exam grade + Grade from the practical component
Exam graded to 20 practical component graded to 4

Concepts in Kinematics and Dynamics of the Rigid Body are presented and developed, illustrated with examples in the context of real life applications. The final objectives are; to be able to understand, apply and conceive gears and machines involving Rigid Body motion. Namely:

a) Knowledge of the laws of Physics that apply to the motion of rigid bodies.
b) Ability to understand gears and other machines involving rigid bodies.
c) Ability to apply the knowledge to real life problems.
