Objectives
THE COURSE AIMS TO PROVIDE AND DEVELOP USEFUL TOOLS FOR A MATHEMATICAL TREATMENT OF THE PROBLEMS AND PHYSICAL PHENOMENA IN THE CONTEXT OF CLASSICAL MECHANICS.
THE COURSE AIMS AT THE FOLLOWING EDUCATIONAL OBJECTIVES:

1) KNOWLEDGE AND UNDERSTANDING
THE STUDENT HAS TO LEARN THE FUNDAMENTAL FACTS OF CINEMATICS AND DYNAMICS OF MATERIAL POINT AND MATERIAL SYSTEM, FREE AND WITH CONSTRAINT.

2) APPLYING KNOWLEDGE AND UNDERSTANDING – ENGINEERING ANALYSIS:
THE AIM OF THE COURSE IS THE ACQUISITION OF GOOD CAPACITY OF FORMULATION AND SOLUTION OF DIFFERENTIAL EQUATIONS DESCRIBING THE DYNAMICS OF MATERIAL SYSTEMS (MATERIAL SYSTEMS PROPERLY MODELED AS: THE MATERIAL POINT, THE RIGID BODY WITH A FIXED AXIS, RIGID BODY WITH A FIXED POINT, THE FREE RIGID BODY).
3) COMMUNICATION SKILLS
ABILITY TO APPLY KNOWLEDGE IN DIFFERENT SITUATIONS THAN THOSE PRESENTED IN THE COURSE AND ABILITY TO REFINE OWN KNOWLEDGE.

4) COMMUNICATION SKILLS – TRANSVERSAL SKILLS:
ABILITY TO EXPOSE ORALLY, WITH APPROPRIATE TERMINOLOGY, THE TOPICS OF THE COURSE.

Prerequisites
FOR THE SUCCESSFUL ACHIEVEMENT OF OBJECTIVES, STUDENTS ARE REQUIRED BASIC MATHEMATICAL KNOWLEDGE, WITH PARTICULAR REFERENCE TO THE CONCEPTS AND TECHNIQUES FOR SOLUTIONS RELATED TO THE THEORY OF INTEGRATION AND RESOLUTION OF ORDINARY DIFFERENTIAL EQUATIONS. KNOWLEDGE OF ALGEBRA AND VECTOR MATRIX THEORY IS ALSO REQUIRED.

Teaching Methods
THE COURSE COVERS THEORETICAL LESSONS, DURING WHICH WILL BE PRESENTED DURING THE COURSE TOPICS THROUGH LECTURES AND CLASSROOM EXERCISES, DURING WHICH PROVIDE THE MAIN TOOLS NEEDED FOR SOLVING EXERCISES RELATED TO THE CONTENT OF THE THEORETICAL ASPECTS.
Verification of learning
THE EXAM IS AIMED AT EVALUATING THE KNOWLEDGE AND THE ABILITY TO UNDERSTAND THE CONCEPTS EXPOSED DURING LESSONS AND THE ABILITY TO APPLY SUCH KNOWLEDGE AND FORMULATE THE DIFFERENTIAL EQUATIONS DESCRIBING THE DYNAMIC OF MATERIAL SYSTEMS.
THE EXAMINATION IS DIVIDED INTO A SELECTIVE WRITTEN TEST AND IN AN ORAL INTERVIEW.
WRITTEN PROOF: THIS LASTS 2 HOURS AND CONSISTS IN SOLVING TYPICAL PROBLEMS PRESENTED IN THE COURSE. IN THE CASE THAT THIS TEST IS SUFFICIENT, IT WILL BE EVALUATED BY THREE SCALES.
ORAL TEST: THIS TEST HAS A DURATION OF APPROXIMATELY 20 MINUTES AND EVALUATES THE ACQUIRED KNOWLEDGE.
IN THE FINAL EVALUATION, EXPRESSED IN THIRTIETHS, THE ASSESSMENT OF WRITTEN TEST WEIGHS FOR 40%, WHILE THE ORAL INTERVIEW WEIGHS FOR THE REMAINING 60%.
LAUDE FOLLOWS FROM BRILLIANT WRITTEN PROOF AND ORAL INTERVIEW.
