(Common to Mechanical and Mechatronics-IV Semester)

OBJECTIVE
• To understand the force-motion relationship in components subjected to External Forces
• To analyse the force-motion characteristics of standard mechanisms
• To study the undesirable effects of unbalances resulting from prescribed motions in mechanism.
• To visualise the effect of Dynamics of Undesirable Vibrations
• To understand the principles in mechanisms used for governing of machines.
