3 1 0 4
OBJECTIVE
· To understand the concept of machines, mechanisms and related terminologies.
· To analyse a mechanism for displacement, velocity and acceleration at any point in a moving link
· To understand the theory of gears, gear trains and cams
· To understand the role of friction in drives and brakes.
UNIT I BASICS OF MECHANISMS 7

(Gruebler’s equation)
-Grashoff's
law-
Kinematic Inversions of four-bar chain and slider crank chain - Mechanical Advantage-
Transmission angle.
Description of common Mechanisms - Offset
slider mechanism as quick return
mechanisms, Pantograph, Straight line generators (Peaucellier and Watt mechanisms),
Steering gear for automobile, Hooke’s joint, Toggle mechanism, Ratchets and escapements -
Indexing Mechanisms.
UNIT II KINEMATIC ANALYSIS
