Objective of the Course:
Dynamic analysis is one of the most important stages in machine design. First step in this is the derivation of equations of motion. In this course, various formulations used to obtain equations of motion. Besides, the dynamics of some mechanisms and machines encountered in mechanical engineering field.

Contribution of the Course to Professional Development
Today, thee exist some softwares for the dynamic analysis of mechanical systems. Fort he efficient use of these softwares, it is necessary to govern the fundamental principles and issues of mechanics and machine dynamics. This course provides the students the opportunity of extention of knowledge in the field of machine dynamics, and learning how to implement in the practice.
21
Learning Outcomes:
1
Students who attend this course can analyse, discuus and develop the general performance of a mechanism which exists or in the stage of design. ;
2
Fundamentals principles of Dynamics apply to mechanisms and machines.;
