3. AIMS OF THE COURSE

4. The first aim of this Course is to give a theoretical and practical base referred to the mechanic systems applied to the machines commonly adopted in the industrial field

5. The second aim is to analize problems related to the management of machines in a production contest (maintenance and troubleshooting)

6. The third aim is to analize problems related to the interfacing of machines with plant utilities and working environment and safety

7. Review Question
What are the aims of this course? 7

8. DEFINITION OF MACHINE, MECHANISM AND KINEMATIC PAIR

9. A machine is a tool containing one or more parts (such as elementary mechanisms) which uses energy to perform an intended action

11. A machine is composed of one or more mechanisms, which transform an input movement into one or more output movements

12. Each mechanism is composed of one or more kinematic pairs, (two elements directly connected) which association imposes fixed constraints on their relative movement

13. These constraints are based on physical relations (kinematics) that regulate the relative motion among one reference point and any other different parts and/or points

14. Review Question
What is a machine? 14

15. KINEMATICS
BASIC CONCEPTS

16. Kinematics is the branch of classical mechanics which describes the motion of points, bodies and systems of bodies linked together without considering the causes of motion

18. Kinematics is also called the "geometry of motion“ as it studies the trajectories of points, parts and other geometric objects together with their differential properties (speed and acceleration)

20. The study of kinematics can be abstracted into the following mathematical functions of single point trajectory and/or geometric (rigid) transformations

21. Review question
Can kinematics just describe the possible movements of a given physical system or also explain the reasons which caused these movements?

22. DYNAMICS, KINETIC ENERGY AND WORK

23. Dynamics is a branch of classical mechanics dealing with the study of forces (or torques) applied to physical systems and their effect on body motion

24. The relationship between a physical system (rigid body) and a system of forces acting upon it (and its consequent motion) is expressed by Newton’s II Law:
F = m*a

25. A force F causes an acceleration a (change of speed) in a body with a certain inertial mass m. The inertial mass can be related to the resistance of the same to be accelerated by a force.

26. Review question
Can dynamics just describe the reasons of movements of a given physical system or also contain the concept of Energy related to these movements?
