Prerequisites:

Knowledge and basic skills of physics (kinematics and dynamics of a point and of a rigid body), of mathematical analysis and linear algebra. 
Target skills and knowledge:

The course aims to provide students with the fundamental technical knowledge (laws, equations, theorems) for mechanical modeling. The course allows acquiring knowledge on the main components for motion generation and power transmission.
The course provides methodologies and tools for solving the kinematic and dynamic analysis of machines, with reference, in particular, to planar motion. 
Examination methods:

The assessment of knowledge and abilities is carried out through a written assessment divided into two parts done in the same day:
 in the first part, through at least two separate openended questions, the student's knowledge of the course topics is ascertained,
 in the second part, through the solution of a practical problem (exercise), the abilities related to mechanical modeling and the computational capabilities are ascertained. 
Assessment criteria:

The evaluation criteria by which the knowledge and abilities acquired will be verified are:
 the completeness of the theoretical knowledge acquired on the course topics;
 the level of autonomy acquired in the interpretation and solution of mechanical of machine problems.
 proved ability to apply theoretical knowledge to the development of kinematic and dynamic models of mechanisms;
 the presentation capabilities and the rigorousness in the discussion of the issues discussed
