Kinematic pairs are those which have
two elements that:
Have line contact
Have surface contact
Permit relative motion
Are held together
Permit relative motion
A kinematic pair or simply a pair is a
joint of two links having relative motion between them.
Hence, the correct option is (C).
&Key Points:-
Types of kinematic pair on basis of
relative motion between links:
●Turning pair ● Sliding
pair
●Rolling pair ●Screw pair
●Spherical pair.
On basis of contact links:
●Lower pair ●Higher pair
●Wrapping pair
On basis of mechanical constraint:
●Closed pair ●Open pair
