The course aims at providing the knowledge of the basics of kinematics, statics and dynamics applied to the study of mechanical systems, and the most relevant aspects of the mechanics of machinery. The student will be able to discuss and analyse the functional, kinematic and dynamic features of transmissions and mechanical drives.
At the end of the course, the student will be able to:
Theoretical and applicative lessons.
Introduction to mechanics of machinery.
Basics of vectorial calculus. Kinematics of the point, kinematics of the relative motions and of the rigid body.
Constraints, kinematic pairs, topology, typology and mobility of the kinematic chains.
Contact forces and friction between solids. Resistance between solids and fluids. Realization of the kinematic pairs.
Kinematics of the planar mechanisms: position and velocity models with analytical and geometrical approaches.
Statics of the rigid body. Statics of the planar mechanisms: constraints and reactive forces; determination of reactive and active forces/moments acting on a mechanism with analytical and geometrical approaches. Force transmission. Virtual work principle.
Fundamentals of dynamics: fundamental laws; Newtonian and energetic approach. Geometry of the masses and kinetic energy of a body. Kinetic energy of multibody systems. Principal types of active forces. Dynamics of mechanical systems with constant transmission ratio with one degree of freedom: power balance, efficiency and power flows; static characteristics; motor-load coupling; usage of mechanical transmissions; reduction to one free coordinate of forces, moments and inertias.

Written exam with escercises and oral exam with discussion about the written exam and other questions.
The written exam consists in exercises of analysis of the morphological and functional features of simple mechanical systems. Indicatively, the exam is composed of two exercises; the first is mainly focussed on kinematics and statics of a mechanism, the second on the dynamic analysis of a motor/transmission/load system. The correctness and the clarity of the calculus procedure is assessed.
In the oral exam, if necessary, the written exam is discussed; moreover, there are other theoretical questions about topics included in the program.
