Q.  How is the kinematic pair formed?(Marks: 01)
- Published on 19 Oct 15

a. when two kinematic links of a machine are in contact with each other and relative motion between them is not completely constrained
b. when two kinematic links of a machine are in contact with each other and relative motion between them is completely constrained
c. both a. and b.
d. none of the above

ANSWER: when two kinematic links of a machine are in contact with each other and relative motion between them is completely constrained
 
When two kinematic links or elements are in contact with each other, they are said to form a pair and if the relative motion between them is completely constrained, the pair is called as kinematic pair.
