A combination of kinematic pairs, joined in such a way that the relative motion between the links is completely constrained, is called a

A structure
B mechanism
C kinematic chain
D inversion

Correct Answer: kinematic chain

When the kinematic pairs are coupled in such a way that the last link is joined to the first link to transmit definite motion (i.e. completely or successfully constrained motion), it is called a kinematic chain. In other words, 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 and the relative motion between the links or elements is completely or successfully constrained.
