The module of Mechanics of Machinery aims to provide the tools necessary for the knowledge and analysis of the fundamental mechanical phenomena present in the mechanical power transmissions and the identification of the main components and mechanical systems used, through a functional analysis.
Fundamentals on kinematic and kinetic-static methods of transmitting machines. Analysis of forces in transmissions in the presence of friction. Lubrication elements. Dynamic analysis of transmissions through elementary models with one or more degrees of freedom. Components constituting the naval transmissions: sliding and rolling bearings, gear wheels and gears, belts, chains, wire ropes, cams, couplings, couplings, brakes.
The aim of the Mechanics of Machinery module is to provide operational concepts on the functionality of mechanical systems used in the industrial field and, in particular, in the naval field. At the end of the cosmos the student will have acquired the knowledge related to the fundamental mechanical problems, with specific reference to the industrial transmissions and will be able to analyze the fundamental problems of the basic mechanical components. Specifically, the student will be able to:
To effectively deal with the topics covered in the course, knowledge of:
The teaching consists of lectures and classroom exercises, carried out in integrated mode on a orientative amount of 60 hours. The theoretical topics treated are associated, individually or in groups, with exercises carried out.
The course program includes the presentation and discussion of the following topics:
The topics covered during the exercises are an integral part of the exam program.

According to the timetable of the Polytechnic School.
The exam consists of a written test and an oral test. The written test will focus on a similar exercise to those treated during the exercises and in a question with an open answer on one of the topics covered in the course. After this test a partial evaluation will be provided (in thirtieths): all the students who have obtained the 18/30 grade are admitted to the oral exam. The students who have obtained a vote in the circle of sufficiency (indicatively at least 16/30) are also admitted to the oral test. The oral exam will complete the exam with the discussion of other topics included in the course. The final evaluation will globally consider the outcome of the answers (written and oral) of the student. The written test has a maximum duration of 60 minutes. The date of the oral test will be announced following the corresponding written test and at the time of communication of the results of the written test, with reference to the number of students participating in the single exam session.
The written test tends to verify the effective acquisition of basic knowledge on the themes of Mechanicis of machinery, through the solution of an easy exercise in line with those carried out during the module and through the written presentation, in summary form, of a theme among those scheduled. The oral exam tends to complete the verification of the student's preparation, with discussion of one or more topics explicitly indicated in the exam program.
The teacher is available for detailed information.
