1.    Links & Mechanism :
       Links : kinematics pairs, higher and lower pairs, constraints, Single slider mechanism, chains, double slider crank mechanism, inversions. Exact straight line mechanism of peaucelliers, Heart and Scott, Roussell approximate straight line mechanisms of grasshopper, watt and Roberts. Pantograph, steering gear mechanisms - condition for corrects s tearing, Davis and Ackerman's steering gears mechanism.
2.    Motion :
       Rectilinear and rotational motion in a plane, compound pendulum, equivalent dynamical system. Velocity and acceleration in machine parts,  instantaneous center, centroode, its laws, velocity and acceleration diagrams for simple kinematics mechanisms. (Vector and graphical approach).
3.    Friction :
       Inclined plane, condition for maximum efficiency, pivot & collar friction, uniform pressure & uniform wear, friction  circle, friction axis. Belt & rope drive effect of centrifugal stress on power transmitted, slip & creep effect, use of Jockey pulleys.
 
4.    Brakes and dynamometers :
       Simple  block brakes, internal expanding shoe brake, band brake, braking of a vehicle transmission types of dynamometer.
5.    Cams :
       Types of cams & followers, displacement, velocity and acceleration of followers, Construction of cam profiles with knife-edge with roller and with flat footed for reciprocating and oscillating followers.
6.    Gear trains :
