Theory of Machines: Displacement, velocity and acceleration analysis of plane mechanisms; dynamic analysis of linkages; cams; gears and gear trains; flywheels and governors; balancing of reciprocating and rotating masses; gyroscope.
DESIGN OF FLYWHEEL INTRODUCTION A flywheel used in machines serves as a reservoir which stores energy during the period when …
Grashof’s law Grashof’s law state that the kinematic chain is a combination of four or more kinematic pairs, such that the …
The Four-Bar chain A four bar chain is the most fundamental of the plane kinematic chains. It is a much …
Grubler’s criterion If we apply the Kutzbach criterion to planer mechanism, then equation of Kutzbach criterion will be modified and …
Kutzbach Criterion DOF of a mechanism in space can be determined as follows: In mechanism one link should be fixed. …
Degrees of Freedom An unconstrained rigid body moving in space can describe the following independent motion: a. Translational motion along …
Types of Joint: The usual types of joints in a chain are: Binary Joint Ternary Joint Quaternary Joint Binary Joint: …
Kinematic Pair When two kinematic links are connected in such a way that their motion is either completely or successfully constrained, …
Types of Links A mechanism is made of a number of resistant bodies out of which some may have motions …
Types of constrained motion: Completely constrained motion: When the motion between a pair is limited to a definite direction irrespective …
