How many degree of freedom does the mechanism shown below has?
0
1
2
3
0
Given :Number of link (l) = 4
Number of binary joints (j) = 4
Number of higher pair (h) = 0
Motion which is not part of mechanism (Fr) = 1
(Redundant motion)
According to Kutzback equation for degree of freedom,
Hence, the correct option is (A).
&Key Points:-
If the mechanism is made like this
shown in below figure,
Then the redundant motion is
eliminated
