Correct Answer - Option 1 : Kinematic inversion

Concept:

Mechanism and Inversion

• When one of the links of a kinematic chain is fixed, the chain is known as mechanism
• It may be used for transmitting or transforming motion e.g. engine indicators, typewriters, etc.
• A mechanism with four links is known as a simple mechanism, and the mechanism with more than four links is known as compound mechanism
• We can obtain as many mechanisms as the number of links in the kinematic chain by fixing, in turn, different links in a kinematic chain.
• This method of obtaining different mechanisms by fixing different links in a kinematic chain is known as inversion of the mechanism.

Kinematic chain

• A kinematic chain may be defined as a combination of kinematic pairs, joined in such a way that each link forms a part of two pairs
• For example, the crankshaft of an engine forms a kinematic pair with the bearings which are fixed in a pair, the connecting rod with the crank forms a second kinematic pair, the piston with the connecting rod forms a third pair and the piston with the cylinder forms the fourth pair. The total combination of these links is a kinematic chain.
