DEPARTMENT OF MECHANICAL ENGINEERING
SUBJECT TITLE WITH CODE: 08AA302 & KINEMATICS OF
MACHINERY
CLASS: II MECH B (JUN11-NOV11)
SEMESTER: III
Aim
To provide the basic knowledge necessary to understand the
mechanism of machines
Objective
To understand the layout of linkages in the assembly of a
system/machine. To study the principles involved in assessing the
displacement, velocity and acceleration at
anypoint in a link of a mechanism
To analyse the motion resulting from a specified set of linkages
in a mechanism.Name of the Faculty: Mrs.S.Veena, APME
