A kinematic pair cannot be classified
on the basis of ________ .
Nature of contact between the links
Nature of constraints between the link
Number of connected links
Type of relative motion between the links
Number of connected links
●Kinematic pair cannot be classified
on the basis of number of connected links.
●According to nature of mechanism
constraint kinematic pairs are classified (permanent closed pair/closed
pair/self-closed pair and unclosed pair/ open pair/ force-closed pair).
●Kinematic pairs can also be
classified according to nature of relative motion. For example, sliding pairs,
turning pair, rolling pair etc.
Hence, the correct option is (C).
&Key Points:-
1. Permanent closed pair : When the elements of a pair are held together
mechanically, it is known as closed pair.
Example : Screw pair
2.Unclosed pair : When two links of
pair are in contact either due to force of gravity or some spring action, they
constitute an unclosed pair.
