CARNEVALE MARCO (titolare) - 9 ECTS

Basic notions from the following courses: Analisi matematica 1, Geometria and Algebra, Fisica 1.

Provide the student with the basic skills necessary for the modeling and analysis of mechanical systems, also in the presence of mechanical transmissions and endothermic, electric and hydraulic propulsion systems.

a) Kinematics of the point, of the rigid body and of systems of rigid bodies in the plane. Constraint classification and pure rolling constraint. Relative motion theorem. Analysis of open and closed kinematic chains with the use of complex numbers: Scara manipulator, ordinary crank mechanism, four bar linkage, oscillating glyph.
b) Statics of the rigid body and of rigid body systems. Static equilibrium equations. Virtual work principle for a system of rigid bodies, in the presence of conservative and non-conservative forces.
c) Mass geometry: centre of gravity and mass moment of inertia. Parallel axis theorem for the moment of inertia.
d) Dynamics of the rigid body and of rigid body systems. Equations of dynamic equilibrium according to D’Alembert. Contact forces: static and sliding friction, rolling resistance. Kinetic energy theorem and power balance.
e) Dynamics of the one-degree-of-freedom machine. Transmission ratio and efficiency, direct and inverse motion, steady state and transient motion. Characteristic diagrams of engines, electric motors and users (resistance forces). Study of the starting transient in the case of linear drive torque.
Study of the longitudinal dynamics of the motor vehicle. Rotor balancing.
f) Vibrations of mechanical systems. Equation of motion of one-degree-of-freedom linear systems. Free motion and forced motion. Role played by damping.

Traditional lesson with the teacher teaching the whole class

FONDAMENTI DI MECCANICA TEORICA E APPLICATA 3/ED
Mc Graw Hill Education
Authors: Nicolò Bachschmid, Stefano Bruni, Andrea Collina, Bruno Pizzigoni, Ferruccio Resta e Alberto Zasso.

The exam consists of a written test and an oral test. The written test consists of two exercises related to the topics addressed in class during the exercises. Only the students who get a positive mark to the written test are admitted to the oral exam, the latter focusing on the entire course program.
