  • If there is all pairs are lower pair of a kinematic chain then 4 pairs required to make a chain.
  • But, if there is atleast one higher pair involved then minimum 3 pairs required to make a kinematic chain. Cam and follower is example of a kinematic chain and it includes total 3pairs.
One higher pair = two lower pair.

Minimum number of kinematic pair required is 3. if all lower pair are consider then 4 but if higher pair taken into consideration then 3
