3 1 0 4 OBJECTIVE:
 To understand the method of static force analysis and dynamic force analysis of
mechanisms
 To study the undesirable effects of unbalances in rotors and engines.
 To understand the concept of vibratory systems and their analysis
 To understand the principles of governors and gyroscopes.
