Syllabus
Prerequisites: Calculus I
Physics
Fundamentals of Linear Algebra and Geometry
Numerical analysis
Calculus II
Target skills and knowledge: The course aims to provide the fundamental skills (laws, equations, theorems) for modeling in the mechanical field.
The course includes the methodologies and tools for solving kinematic analysis and machine dynamics problems, with particular emphasin on plane motion.
Examination methods: The exam focuses on the entire program and consists mainly of a written test, which includes both numerical exercises and theory questions.
Approximately there are 2-3 exercise questions and 2-3 theory questions. Each question is associated with a score that appears in the exam track, so that the student can have an indication of the score he can reach.
The total duration of the written test is at least 2 hours.
The oral exam is only foreseen in three cases
a) If the result in the written test is 16 or 17/30. In this case, the student is given the opportunity to achieve sufficiency by an oral exam on the date indicated by the teacher.
b) If the student wishes to improve any sufficient mark obtained in the written test, even in this case the oral test must be sustained in the same appeal on the date indicated by the teacher.
c) If the student obtained a very negative mark (<10/30) in a previous written test, even in this case the oral test must be sustained in the same appeal on the date indicated by the teacher.
Assessment criteria: To pass the exam the student must demonstrate the ability of analyzing mechanical systems, the ability of dividing complex systems into subsystems, the ability of understanding the physical phenomena that govern kinematics and dynamics of mechanical systems.
In detail, numerical exercises are evaluated positively if the calculation method and hypothesis are correct and the final result is correct.
The answers to the theory questions are evaluated positively, if the physical / mathematical treatment is correct, the exposure is clear and the treatment is complete.
